Radiology Room Design & Shielding Calculation Service in Nigeria

H1: Radiology Room Design & Shielding Calculation Service in Nigeria - Price, Providers, Scope & SLA

Radiology Room Design & Shielding Calculation is a specialized engineering service that ensures your new or upgraded radiology suite is designed for optimal clinical workflow and, most importantly, that its walls, doors, and viewing windows have the correct lead or concrete thickness to protect staff and the public from radiation. This is mandated by the Nigerian Nuclear Regulatory Authority (NNRA). This service is non-negotiable for any hospital, diagnostic centre, or clinic in Nigeria installing or replacing imaging equipment like a GE Revolution CT, a Siemens MAGNETOM MRI, or a simple general X-ray machine. You need this to avoid costly construction rework, pass mandatory NNRA inspections, guarantee the safety of your personnel and patients, and prevent project delays that can run into months and millions of Naira. We see facilities from large federal teaching hospitals in Abuja and Lagos to private diagnostic chains and NGO-run clinics in more remote states requiring this service to secure their essential Certificate of Registration from the NNRA before they can legally operate their equipment.

H2: Radiology Room Design & Shielding Calculation price in Nigeria

Ad-hoc, single-room shielding calculations with a basic layout drawing typically cost between NGN 500,000 and NGN 1,500,000. A more comprehensive bundled service, which includes detailed architectural drawings, mechanical and electrical (M&E) plans, and direct support for your NNRA submission, ranges from NGN 2,000,000 to NGN 5,000,000 per room. A full turnkey project management service—covering everything from initial site assessment and design to construction supervision and final NNRA certification—can start from NGN 7,000,000 and increase based on the complexity of the equipment. For instance, designing a suite for a Varian TrueBeam linear accelerator is significantly more complex and costly than for a standard mammography unit. The final price is driven by the equipment's radiation output, the room's location (a ground-floor room is simpler to shield than one on an upper floor), your projected patient workload, and the level of documentation required for donor reporting (e.g., for USAID or Global Fund projects).

• Cost levers you control:
  • Providing accurate architectural "as-built" drawings of your facility at the start.
  • Finalizing the exact equipment model (e.g., a Siemens Somatom go.Up CT has different shielding needs than a Canon Aquilion Prime SP) before calculations begin.
  • Grouping the design of multiple rooms (e.g., X-ray, CT, and Mammo) into a single project to benefit from a volume discount.
  • Confirming your power availability and quality early to prevent costly redesigns for UPS and stabilizers.
  • Engaging the design service before construction starts, not as an afterthought.

H3: cheapest Radiology Room Design & Shielding Calculation in Nigeria

The absolute minimum cost for a basic shielding calculation report from a freelance physicist might be NGN 250,000 - NGN 450,000 per room. This price typically only gets you a calculation sheet with the required lead thickness values. It almost always excludes critical components like detailed CAD drawings, site visits for verification, professional indemnity insurance, or any support if the NNRA has questions or rejects the submission. The risk is that any error in the calculation or its interpretation by your builder falls entirely on you, leading to expensive rework, project delays, and the potential failure of your NNRA inspection. Hidden costs emerge when you have to pay separately for drawings, site visits, and resubmission support, often exceeding the cost of a proper, bundled service.

• Checklist before accepting low quotes:
  • Is the provider a CAC-registered company with a physical office, or just an individual?
  • Can they provide a current, verifiable NNRA license for providing radiation protection advisory services?
  • Will you receive professionally stamped and signed architectural drawings, or just a spreadsheet?
  • Does the quote explicitly include at least one physical site visit for measurement verification?
  • What is their written policy if the NNRA requests modifications to the design? Is the rework included in the price?

Avoid the risks of non-compliance by working with a verified, professional service provider.

H3: affordable Radiology Room Design & Shielding Calculation in Nigeria

A value-optimized, affordable package for a standard diagnostic facility with one or two modalities (e.g., a general X-ray and a CT scanner) costs between NGN 1,800,000 and NGN 3,500,000. This approach bundles all the essential services required for compliance and operational readiness, giving you a predictable cost and outcome without the expense of full turnkey project management. It focuses on delivering a compliant, buildable design that your contractors can execute and the NNRA will approve, ensuring the best return on your investment.

H3: Radiology Room Design & Shielding Calculation contract cost in Nigeria (AMC vs CMC)

This service is a one-time project, so it is not procured through an Annual Maintenance Contract (AMC) or Comprehensive Maintenance Contract (CMC), which are used for equipment upkeep. Instead, it is governed by a project-based contract with milestone payments. For a large-scale hospital project, this might be structured with an initial design and calculation phase costing NGN 1,500,000 - NGN 4,000,000. Subsequent payments are then tied to specific deliverables like construction supervision (e.g., NGN 500,000 - NGN 1,000,000 per month) and a final payment upon successful commissioning and NNRA certification (e.g., NGN 1,000,000 - NGN 2,500,000). This phased approach provides better cash-flow management for you and ensures the provider is committed through to the final regulatory approval.

Feature	One-Off Project Fee	Phased Milestone Contract
Cash Flow	Single, large upfront payment	Payments spread across project timeline
Scope	Best for single, simple rooms	Ideal for multi-room or complex projects
Flexibility	Less flexible to design changes	More adaptable to evolving project needs
Provider Accountability	High at the start, may reduce after delivery	Consistently high throughout the project

A milestone-based contract is the recommended approach for any significant radiology project.

best Radiology Room Design & Shielding Calculation provider in Nigeria

The best providers are established medical physics or specialized engineering firms with a verifiable public record of successful NNRA certifications for complex modalities like CT, MRI, LINACs, and Cath Labs. Top-tier providers are often technical partners for major OEMs like GE Healthcare, Siemens Healthineers, or Philips, as they are intimately familiar with the specific site planning requirements for models like the GE Signa MRI or the Siemens Artis Q ceiling C-arm. They differentiate themselves not just by producing a calculation, but by providing comprehensive project support, coordinating with your architects and M&E contractors, and ensuring the final built environment is both safe and clinically efficient.

• How to validate provider claims:
  • Request their NNRA license number and independently verify it on the NNRA website or by calling their office.
  • Ask for specific case studies of projects involving the exact equipment model you are installing.
  • Insist on speaking directly to the Chief Radiographer or Biomedical Engineer at one of their reference sites.
  • Request a redacted sample of a final report and drawing package so you can assess the quality and detail of their work.
  • Confirm they have full-time, qualified staff, not just a list of part-time consultants.

Radiology Room Design & Shielding Calculation scope of work in Nigeria (SOW)

A standard Scope of Work (SOW) includes an initial site assessment, a workload calculation based on your projected patient throughput, shielding calculations for all barriers (walls, doors, ceiling, floor, and control console), and the creation of detailed CAD drawings showing the room layout and shielding specifications. The SOW culminates in a final, signed report ready for your NNRA submission. A typical project, from the initial site visit to the delivery of the final report, takes 2-4 weeks, provided you supply the necessary information promptly. The SOW must also include a post-construction verification survey, which is a critical step before the NNRA will issue a license to operate.

• Non-negotiables in the SOW:
  • A clause explicitly guaranteeing that the design, if built as specified, will meet all NNRA requirements for licensing.
  • Clear specification of shielding materials (e.g., "Code 5 lead," concrete density in kg/m³).
  • Inclusion of detailed drawings showing the placement of electrical conduits, AC units, and other penetrations to ensure they are properly shielded.
  • A defined timeline for the delivery of all draft and final documents.
  • A commitment to perform a final on-site shielding integrity survey after construction is complete but before the equipment is used on patients.

how Radiology Room Design & Shielding Calculation works in Nigeria (process & methodology)

The process begins with the medical physicist collecting data on your specific imaging equipment (e.g., the maximum kVp and mA of a GE AMX 240 mobile X-ray) and your projected patient workload (patients per day). Using this data, the physicist applies internationally recognized methodologies, such as those outlined in NCRP Report 147, and specialized software to calculate the required thickness of lead, concrete, or other materials for every barrier. This ensures that radiation levels in adjacent areas fall safely below the strict dose limits set by the NNRA for both staff (controlled areas) and the general public (uncontrolled areas). The calculations account for the type of radiation (primary and secondary), the distance from the source, and how frequently the adjacent areas are occupied.

• Methodology checklist:
  • Is the calculation based on the specific make and model of your equipment?
  • Does the calculation correctly apply the "Use Factor" (U) for each barrier?
  • Does it use appropriate "Occupancy Factors" (T) for all surrounding areas (e.g., an office vs. a public corridor)?
  • Are separate calculations provided for primary radiation (the direct beam) and secondary radiation (scatter and leakage)?
  • Is the final report signed, stamped, and dated by a named, NNRA-licensed medical physicist?

Radiology Room Design & Shielding Calculation SLA in Nigeria (response & uptime targets)

For this project-based service, the Service Level Agreement (SLA) is defined by project milestones and deliverable timelines, not the typical equipment uptime or response time metrics. A standard SLA would contractually commit the provider to specific deadlines. For example: an initial site survey to be conducted within 5 working days of contract signing; the draft report and drawings to be delivered within 10 working days of the survey; and the final NNRA-ready package to be issued within 3 working days of receiving your final comments. The SLA should also include a commitment to respond to any queries from the NNRA regarding the submission within a specified timeframe, typically 48 hours, to keep your application moving forward.

• SLA clauses to include:
  • A clear project timeline with dates for each key deliverable (e.g., "Draft Drawings: 15-Oct-2023").
  • A defined number of design revisions (e.g., two rounds) included in the contract price.
  • A commitment to respond to your queries and NNRA queries within 48 business hours.
  • A penalty clause, such as a 1% fee reduction for each week of delay on major milestones attributable to the provider.
  • A clear escalation path, naming the contacts to be involved if project timelines are at risk.

Franance provides a transparent, milestone-driven SLA for every design project, tracked on your dashboard, so you always know the precise status of your deliverables and your project timeline.

Radiology Room Design & Shielding Calculation documentation and certificates in Nigeria

Upon completion of the service, you will receive a comprehensive documentation package that includes the formal Shielding Design & Integrity Assessment Report, professionally stamped architectural and M&E drawings (in both PDF and editable CAD formats), and all necessary supporting calculations for your NNRA license application. The ultimate goal of this documentation is to enable you to obtain the key certificate: the NNRA's "Certificate of Registration" for your facility, which legally permits you to operate your new imaging equipment. After construction, you will also receive a "Shielding Integrity Survey Report" which confirms the room was built to specification and is safe for use.

• Files auditors demand:
  • The final, signed Shielding Calculation Report from the medical physicist.
  • "As-built" drawings that reflect the final, constructed room.
  • The post-construction Shielding Integrity Survey Report.
  • The NNRA Certificate of Registration for the facility and the specific equipment.
  • The facility's Radiation Safety Program manual, including the "Local Rules" for that specific room.

Radiology Room Design & Shielding Calculation compliance in Nigeria (NAFDAC, SON/SONCAP, NNRA, IEC/ISO)

The primary and most critical regulatory body you must satisfy for room design and shielding is the Nigerian Nuclear Regulatory Authority (NNRA). While NAFDAC regulates consumables and SON (via its SONCAP program) governs the standards for imported equipment at the port, the NNRA holds the sole mandate for radiation safety and the licensing of all radiological facilities. Your design must strictly adhere to the NNRA's safety guides and regulations, which are harmonized with international standards from the International Atomic Energy Agency (IAEA) and the International Commission on Radiological Protection (ICRP). The compliance pathway is clear: submit the design for NNRA review before construction, build according to the approved design, and then pass an NNRA inspection to receive your license to operate.

• Compliance actions per authority:
  • NNRA: Submit the shielding design for review and "No Objection." Apply for an import permit for the equipment. After installation, apply for registration and schedule a facility inspection.
  • SON: Ensure your equipment supplier provides a valid SONCAP Certificate (or Product Certificate and SONCAP) required for customs clearance at the port of entry.
  • Federal Ministry of Health (FMoH): Ensure your overall facility layout and design comply with their guidelines for healthcare facilities.
  • State/Local Planning Authority (e.g., LASPPPA in Lagos): Obtain all necessary building permits using the approved architectural drawings from the design process.

Radiology Room Design & Shielding Calculation preventive maintenance checklist in Nigeria

The design service itself is a one-time project and does not have a preventive maintenance (PM) schedule. However, the physical room that results from the design requires annual checks as part of your facility's mandatory Radiation Safety Program. This maintenance is crucial to ensure the shielding's integrity is maintained over time. The annual check should be performed by or supervised by your Radiation Safety Officer (RSO) and documented thoroughly.

• Core PM tasks (for the shielded room):
  • Annually: Visually inspect all lead-lined surfaces, doors, and windows for any cracks, sagging, or damage. Pay close attention to the seams of lead sheets and the frame of the lead door.
  • Annually: Perform a functional check of all safety features, including door interlocks (if present) and radiation warning lights, to ensure they work correctly.
  • Annually: Conduct a radiation survey with a calibrated survey meter around the perimeter of the room (especially at doors and windows) while the equipment is in operation to detect any potential radiation leaks.
  • Post-Maintenance: If any work has been done that could breach the shielding (e.g., running new electrical conduit through a wall), a re-survey of that specific area is mandatory before resuming clinical use.

Radiology Room Design & Shielding Calculation emergency repair in Nigeria

Emergency repairs are not for the design service, but for the physical shielding itself. If the shielding is breached—for example, a wall is damaged by an equipment trolley or a contractor drills through a lead-lined wall—you must immediately stop using the imaging equipment in that room. The emergency process is to power down the equipment, cordon off the area, and immediately contact a licensed medical physics service provider to perform an emergency radiation survey. They will assess the extent of the breach and provide a documented remediation plan. This plan, along with a formal incident report, must be communicated to the NNRA. You cannot resume operations until the shielding is repaired and certified as safe by the physicist.

• Emergency playbook (for a shielding breach):
  • Immediately power down and lock out the radiology equipment.
  • Notify the hospital's designated Radiation Safety Officer (RSO).
  • Contact your medical physics service provider (like Franance) for an emergency site visit and survey.
  • Thoroughly document the incident, including the date, time, cause, and immediate actions taken.
  • Do not use the room until the repair is complete and a physicist has provided a written report confirming the shielding integrity has been restored.

Radiology Room Design & Shielding Calculation spare parts and logistics in Nigeria

The "spare parts" for this service are the shielding materials themselves: primarily lead sheets, lead-lined doors, and lead glass for viewing windows. Lead sheets are specified by "code" (e.g., Code 4 is 1.8mm thick, Code 5 is 2.24mm thick) and are generally available from suppliers in Lagos and Abuja. However, custom-sized lead-lined doors and large lead glass windows are often imported and can have lead times of 4-8 weeks, which must be factored into your project timeline. It is critical to order materials that exactly match the specifications in the physicist's report; using a lower-grade material will cause your facility to fail its NNRA inspection. Logistics for transporting these heavy materials to sites outside major commercial hubs can be challenging and costly, so this must be planned in advance.

• Spare parts controls (for shielding materials):
  • Always procure materials based on the exact specifications in the signed shielding report. Do not allow your builder to substitute.
  • Insist on a certificate of conformity from the supplier for the lead's purity and thickness.
  • Factor in the logistics costs and potential delays for transporting heavy materials to your specific project site.
  • Ensure your building contractor has proven experience in installing lead shielding. Incorrect installation with gaps at joints is a common point of failure.
  • Plan for customs clearance time and potential SONCAP issues if importing specialized doors or glass.

Radiology Room Design & Shielding Calculation training and handover in Nigeria

The formal handover for a design project is a walkthrough of the completed room with your team (radiographers, RSO) and the medical physicist. The training component is a crucial 1-2 hour session focused on explaining the "Local Rules" and the specific radiation safety features of the newly constructed room. This session covers the boundaries of the designated "Controlled Area," the correct operation of shielded doors and warning systems, and the emergency procedures to follow. This ensures your clinical team understands how to operate safely within the environment that has been designed for them.

• Training deliverables:
  • A signed handover document confirming the room has been inspected and is built to the approved specifications.
  • A final copy of the "as-built" drawings for your records.
  • A documented training session for all relevant staff, with an attendance sheet for your compliance files.
  • A laminated copy of the "Local Rules" and other required safety notices to be displayed prominently in the control area.
  • Clear identification and contact details for the facility's Radiation Safety Officer (RSO).

Radiology Room Design & Shielding Calculation asset inventory and CMMS in Nigeria

While the design service itself is not a physical asset, the resulting shielded room and its key components should be logged in your hospital's Computerized Maintenance Management System (CMMS). Creating an asset record for "CT Scanner Room - Shielding" or "General X-ray Room 1" allows you to schedule and track the mandatory annual radiation safety surveys, maintenance on the lead-lined door, and any repairs. This creates a permanent, auditable record of compliance, which is invaluable during NNRA inspections or internal audits.

• CMMS data points:
  • Asset Name: CT Scanner Room - Shielding
  • Asset ID: [Your hospital's unique ID]
  • Date of Commissioning: [Date of final NNRA approval]
  • Linked Documents: Upload the final shielding report and the NNRA registration certificate.
  • Scheduled PM: "Annual Radiation Safety Survey" - recurring every 12 months.
  • Service Provider: [Name of Medical Physics Provider, e.g., Franance]
  • Maintenance History: Log all annual surveys, repairs, and incidents related to the shielding.

Radiology Room Design & Shielding Calculation power audit and UPS/stabilizer sizing in Nigeria

A critical component of the room design phase is the electrical load calculation, which serves as a dedicated power audit for the new imaging equipment. The process involves analyzing the manufacturer's site planning documents for the specific system (e.g., a Philips Incisive CT has different power needs than a GE Optima) to determine its peak power draw (kVA), voltage tolerance, and earthing requirements. This data is essential to correctly size the Uninterruptible Power Supply (UPS), voltage stabilizer, and dedicated "clean" earth connection. Getting this right is non-negotiable for protecting multi-million Naira equipment from Nigeria's unstable power grid and ensuring consistent diagnostic image quality.

• Power audit outcomes:
  • A specification sheet for the required UPS, detailing the kVA rating and necessary runtime (e.g., 10 minutes to allow for a safe shutdown).
  • A specification for the required servo-motor or static voltage stabilizer.
  • The required specifications for the dedicated electrical circuit, including wire gauge and circuit breaker rating.
  • A specification for the dedicated technical earth, including maximum impedance (e.g., <1 Ohm).
  • Clear placement of Emergency Power Off (EPO) buttons in the room design drawings.

Radiology Room Design & Shielding Calculation relocation and commissioning in Nigeria

If you are relocating existing radiology equipment to a new site, a completely new shielding design and calculation for the new room is mandatory. You cannot assume the shielding from the old location is adequate. The process requires a physicist to assess the new room, its construction materials, and its surrounding areas to calculate the specific shielding needed. The design phase itself takes 2-4 weeks, but the entire relocation project—including de-installation, transport, new room construction, re-installation, and commissioning—can take 2-3 months. You must also formally notify the NNRA of the plan to relocate a registered radiation source and get their approval before moving the equipment.

• Relocation safeguards:
  • Budget for a new shielding design. It is a mandatory regulatory requirement.
  • Complete the new shielding design before starting any construction at the new site.
  • Submit the new design and a relocation plan to the NNRA for approval.
  • Use a logistics company experienced in moving sensitive, heavy medical equipment to prevent damage during transit.
  • After re-installation, the equipment must undergo full commissioning and acceptance testing, followed by a shielding integrity survey, before it can be used on patients.

Radiology Room Design & Shielding Calculation deinstallation and disposal in Nigeria

When decommissioning a radiology room, the original design documentation is essential for guiding the safe removal of hazardous materials, particularly the lead sheeting in the walls and doors. The de-installation process must comply with NNRA regulations for the disposal of the radiation source (the X-ray tube) and state environmental laws (e.g., LASEPA in Lagos) for the disposal of lead waste. This requires a licensed service provider to manage the process, which can cost between NGN 300,000 and NGN 1,000,000 or more, depending on the room's size and the complexity of removal. A formal chain-of-custody for the decommissioned X-ray tube is required by the NNRA.

• Decommission essentials:
  • Formally notify the NNRA in writing of your intent to decommission the equipment and facility.
  • Contract a licensed provider to remove, transport, and dispose of the radiation source.
  • Obtain a "Certificate of Disposal" for the source and keep it in your records indefinitely.
  • Ensure the lead shielding is removed and disposed of in accordance with local environmental regulations.
  • Update your facility's asset register and NNRA license to reflect that the equipment has been decommissioned.

Radiology Room Design & Shielding Calculation quality control and performance verification in Nigeria

The primary quality control (QC) and performance verification for the design service is the post-construction "Shielding Integrity Survey." This is a mandatory test performed after the shielding is installed and the imaging equipment is in place, but before any patients are scanned. A medical physicist uses a calibrated radiation survey meter to take measurements at specified points outside the room (at the door, control window, adjacent walls) while the X-ray equipment is operated at its highest power settings. The purpose is to verify that the radiation levels are below the legal dose limits set by the NNRA, confirming the room was built correctly according to the design.

• QC checkpoints:
  • Radiation dose rate measurements at the operator's control console.
  • Measurements around the entire perimeter of the lead-lined door, especially at the seams.
  • Measurements at the center and edges of the lead glass viewing window.
  • Measurements in all adjacent rooms, as well as on the floors directly above and below the suite.
  • A final, signed report that explicitly states whether all readings are below the regulatory limits and the room is safe for use.

Radiology Room Design & Shielding Calculation electrical safety testing in Nigeria

As part of the final commissioning of the room, a full electrical safety test must be performed on the newly installed imaging equipment according to the IEC 60601-1 standard. While this test is typically conducted by the OEM's installation engineer, the room design must provide the correct electrical infrastructure to enable the equipment to pass. This includes providing a dedicated power circuit with the correct voltage and current rating, and most importantly, a low-impedance "technical earth" connection that is separate from the building's general electrical earth. Failure to provide the correct earthing is a common cause of equipment malfunction and electrical safety test failure in Nigeria.

• Electrical safety deliverables (from the design):
  • A specification for a dedicated, "clean" earth connection with an impedance of less than 1 Ohm.
  • Correctly rated wiring and circuit breakers as specified in the manufacturer's site planning guide.
  • Clearly marked and accessible Emergency Power Off (EPO) buttons at the operator's console and within the room.
  • A final Electrical Safety Test report for the installed imaging equipment, provided by the installation engineer.
  • Permanent, clear labeling of all electrical panels and circuits feeding the imaging equipment.

Radiology Room Design & Shielding Calculation KPIs and reporting in Nigeria

The Key Performance Indicators (KPIs) for this project-based service are focused on timeline adherence and regulatory success. The primary KPIs are "On-Time Delivery of Milestones" (Target: 100%) and "First-Pass NNRA Submission Acceptance" (Target: >95%). Reporting is typically tied to project milestones, with the provider issuing a draft design report for your review, a final design report for construction, and a final post-construction verification report for your compliance records. For NGO or donor-funded projects, all reports must be prepared in a format suitable for submission to funding partners like the Global Fund, CDC, or USAID, which often have specific reporting templates and requirements.

• KPIs to review monthly (during the project):
  • Milestone Achievement: Is the project on, ahead of, or behind the agreed schedule?
  • RFI Turnaround Time: Are your team's technical queries being answered by the provider within the agreed 48-hour window?
  • Budget vs. Actual: Are there any change orders or unforeseen costs impacting the budget?
  • Regulatory Status: What is the current status of the submission with the NNRA?
  • Documentation Readiness: Are all documents being prepared and stored in a way that meets donor reporting standards?

Radiology Room Design & Shielding Calculation payment terms in Nigeria
