What are Lead Aprons & Shields?
Lead Aprons & Shields are personal protective equipment (PPE) designed to protect healthcare workers, patients, and technicians from harmful, scattered ionizing radiation during medical procedures that use X-rays, such as fluoroscopy, radiography, CT scans, and interventional procedures. They are used daily by radiologists, radiographers, cardiologists, surgeons, and other clinical staff working in radiology departments, catheterization labs, operating theatres, and intensive care units. Their primary clinical impact is the significant reduction of the cumulative radiation dose received by personnel, which directly lowers the long-term risk of developing radiation-induced health issues like cancer and cataracts.
Lead Aprons & Shields price in Nigeria
Prices for radiation protection equipment in Nigeria range from NGN 80,000 - NGN 250,000 for standard frontal lead aprons, NGN 150,000 - NGN 450,000 for full wrap-around aprons, and NGN 500,000 - NGN 2,500,000 or more for large mobile shields. The final price is driven by several factors, including the core material (traditional lead vs. lighter, more expensive composite or lead-free alternatives), the lead equivalency rating (0.25mm, 0.35mm, or 0.5mm Pb), the brand reputation (e.g., Kiran, Infab, Bar-Ray), and the specific type of shield. Additional costs such as international freight, customs duties, and foreign exchange rates significantly influence the landed cost in Nigeria. When requesting a quote, ensure it itemizes the apron, any included accessories like thyroid collars, warranty terms, and delivery costs to your facility.
- Questions savvy buyers ask:
- What is the core material of the apron (lead-vinyl, composite, or lead-free) and what is its weight in kilograms for my specified size?
- Does the quoted price include a matching thyroid collar with the same lead equivalency?
- What is the manufacturing date of the apron? (Aprons have a limited lifespan).
- Can you provide the manufacturer's certificate of conformance and radiation attenuation test report for this specific model?
- What is the warranty period, and what specific defects does it cover?

cheapest Lead Aprons & Shields in Nigeria
The cheapest, safest options are basic frontal aprons with 0.25mm or 0.35mm Pb equivalency, typically costing between NGN 80,000 and NGN 150,000. These are almost always made from heavier, traditional lead-vinyl material, which can cause significant fatigue and musculoskeletal strain for staff who wear them for extended periods. Be aware of hidden costs; the lowest-priced aprons often do not include a thyroid collar, which is an essential piece of protection and must be purchased separately. Warranty on these entry-level models is often limited to one year and may not cover wear and tear on the outer fabric.
- Before accepting the lowest quote:
- Verify the lead equivalency (mm Pb) is clearly stated on the apron's tag.
- Check the manufacturing date to ensure you are not buying old stock.
- Ask about the durability and cleaning instructions for the outer material.
- Confirm that the apron meets the basic personal protective equipment guidelines set by the Nigerian Nuclear Regulatory Authority (NNRA).
To ensure you get a safe and compliant apron without overpaying, contact Franance for a vetted, cost-effective quote.
affordable Lead Aprons & Shields in Nigeria
The most affordable and best-value options are bundles that include a lightweight composite frontal apron (0.5mm Pb), a matching thyroid collar, and a proper apron storage rack, with set prices typically ranging from NGN 200,000 to NGN 380,000. While the initial cost is higher than the cheapest apron, this approach significantly lowers your 12-month costs. A lightweight apron reduces staff fatigue, which is linked to higher productivity and fewer work-related injuries. More importantly, using a storage rack prevents cracks in the internal lead lining, potentially extending the apron's safe, usable life by 30-50% and delaying a costly replacement.
- Bundle these for value:
- Apron + Thyroid Collar: Ensure every apron is purchased with its own collar.
- Department Set: Order 5-10 aprons with a multi-apron mobile or wall-mounted rack.
- Full Protection Kit: Combine an apron, collar, and leaded glasses for high-exposure roles.

new Lead Aprons price vs used Lead Aprons price
New lead aprons range from NGN 80,000 to NGN 450,000+, while used or "refurbished" lead aprons are not sold in the professional market and should be avoided at all costs. The concept of a "refurbished" lead apron is a dangerous misnomer. Unlike electronic equipment, the integrity of a lead apron cannot be reliably restored. Used aprons carry an unknown history and a high risk of invisible micro-cracks or material degradation that renders them ineffective, exposing your staff to direct radiation hazards. New aprons provide a manufacturer's warranty, a guaranteed level of protection certified by the OEM, and compliance with NNRA regulations.
| Feature | New Lead Apron | Used Lead Apron |
|---|
| Safety | Guaranteed protection as per tag | Compromised; high risk of cracks |
| Warranty | 1-2 year manufacturer warranty | None |
| Compliance | Meets NNRA standards | Fails NNRA audit requirements |
| Lifespan | Full 5-7 year expected lifespan | Unknown; potentially zero |
| Price | NGN 80k - 450k+ | Deceptively low, but infinite risk |
For guaranteed safety and compliance, always procure new, certified lead aprons through a trusted supplier like Franance.

Lead Aprons & Shields specifications
The 5-6 most decisive specifications that impact clinical safety, user comfort, and long-term value are Lead Equivalency, Core Material, Weight, Design Type, and Outer Fabric.
- Lead Equivalency (mm Pb): This measures the radiation-blocking capability. The standard for frontal protection in fluoroscopy is 0.5mm Pb. For the back of wrap-around aprons, 0.25mm Pb is common. Anything less than these standards for the respective applications is non-compliant for high-use areas.
- Core Material: This determines the apron's weight. Standard Lead-Vinyl is the heaviest and cheapest. Lightweight Lead Composite blends lead with other lighter metals, reducing weight by up to 20%. Lead-Free (bismuth, antimony) is the lightest option, reducing weight by up to 35%, but is also the most expensive.
- Weight: For an average-sized adult, a standard apron can weigh 6-8 kg, while a lightweight version is 4-6 kg. This 2 kg difference has a massive impact on reducing fatigue and musculoskeletal strain over a full workday.
- Design Type: Frontal Aprons protect the front of the body and are suitable for general radiography. Wrap-Around Aprons provide protection from the front and back, which is essential in interventional suites and operating theatres where scatter radiation comes from all directions.
- Outer Fabric: Look for non-porous, durable, and easily cleanable fabrics like nylon or specialized anti-microbial coatings to ensure longevity and infection control.
- Specs that change outcomes:
- Core Material: Directly impacts staff fatigue, comfort, and long-term health.
- Lead Equivalency: The fundamental determinant of radiation safety.
- Sizing & Fit: An ill-fitting apron creates gaps in protection, rendering it ineffective.
- Design Type (Frontal vs. Wrap-Around): Choosing the wrong type for the procedure room exposes staff to unnecessary risk.
Lead Apron Sizing, Care, and Inspection in Nigeria
Proper implementation of lead aprons involves a three-part process: correct initial sizing and fitting for all staff, comprehensive training on daily care and storage, and establishing a mandatory annual inspection and testing protocol. There is no physical installation. Sizing must be done using the manufacturer's specific measurement charts to ensure there are no gaps in coverage around the torso and shoulders. Staff must be trained to hang aprons on designated, approved racks immediately after use; folding an apron will cause the internal lead to crack and must be strictly forbidden. Your facility's Radiation Safety Officer (RSO) must implement an annual inspection program that includes a visual check for tears and a fluoroscopic scan to detect internal cracks.
- Do not sign off until you have…
- Physically verified the size of each apron matches the order and fits the intended user.
- Checked the manufacturing date on the tag of every single apron.
- Received the OEM's Certificate of Conformance for the batch.
- Confirmed the lead equivalency (e.g., "0.5mm Pb Eq") is clearly and permanently marked on the tag.
- Received a proper invoice and warranty documentation from the supplier.

Lead Aprons & Shields delivery and logistics in Nigeria
Delivery of lead aprons from international manufacturers via air freight typically takes 4 to 8 weeks, a timeline that includes production, shipping, and Nigerian customs clearance. Local suppliers who hold stock in Lagos or Abuja can often deliver to your facility within 2 to 5 business days. When ordering, it is critical to confirm that the supplier is handling all import permits, customs duties, and inland logistics. Your quote should be on a Delivered Duty Paid (DDP) basis, meaning the price includes delivery to your hospital's doorstep, protecting you from unforeseen clearance costs or delays at the port.
- Logistics risk controls:
- Confirm in writing that the quote is DDP to your specific facility address.
- Request an air waybill (AWB) number to track the shipment once it leaves the country of origin.
- Verify the shipment is insured against damage or loss during transit.
- Upon arrival, immediately inspect the packaging and the aprons for any damage before signing the delivery note.
Lead Apron warranty and service in Nigeria
Standard manufacturer warranties for lead aprons typically cover defects in materials and workmanship for a period of one to two years. This includes issues like faulty buckles, seam splitting, or premature material degradation. However, the warranty is almost always voided by improper use or storage. Specifically, any damage, such as cracks in the internal lead lining caused by folding the apron, is not covered. There are no "repair" services for a compromised lead apron; once the protective core is cracked, the apron must be taken out of service and replaced immediately. Service, therefore, revolves around your internal program of proper care, storage, and annual inspection.
- Warranty terms to insist on:
- A clear, written warranty for a minimum of one year covering manufacturing defects.
- A clear statement from the supplier on actions that void the warranty (e.g., folding, improper cleaning).
- Confirmation of the process for making a warranty claim with the local Nigerian supplier.
Inspecting and Replacing Old Lead Aprons in Nigeria
Old lead aprons should be replaced according to the manufacturer's recommended lifespan, typically every 5-7 years, or immediately if they fail an inspection. There is no safe "refurbished" or "second-hand" market for lead aprons. You must always buy new to guarantee protection. The integrity of an apron must be checked annually by your Radiation Safety Officer or a trained radiographer. This involves a thorough visual inspection for any tears, holes, or stiffness, followed by a fluoroscopic or radiographic examination. To do this, lay the apron flat on the X-ray table and use a low kVp setting to scan its entire surface. Cracks, holes, or thinning in the lead will appear as dark lines or patches, indicating the apron is compromised and must be disposed of.
- Signs an apron needs immediate replacement:
- Visible tears, punctures, or rips in the outer fabric that could expose the inner lining.
- Stiffness, brittleness, or a "cracking" sound when handled, suggesting the inner material is degrading.
- Failing a fluoroscopic inspection by showing dark lines (cracks) or areas of reduced density.
- The apron is older than the manufacturer's stated maximum lifespan (check the tag for the manufacturing date).
original vs fake Lead Aprons - how to verify in Nigeria
You can verify the authenticity of a lead apron by ensuring it has a permanently affixed, professionally printed manufacturer's tag and by purchasing exclusively from authorized distributors of reputable brands. The tag is the most critical feature; it must clearly state the brand name (e.g., Kiran, Infab), the model, the exact lead equivalency (e.g., 0.5mm Pb Eq Frontal), the manufacturing date, and a serial number. Be highly suspicious of aprons with missing, hand-written, or poorly printed tags. The most significant red flag is an unusually low price, as authentic radiation protection materials are expensive. If a deal seems too good to be true, the apron is likely fake or non-compliant and offers little to no real protection.
- Spot counterfeit risk:
- The apron has no manufacturer's tag or a tag that looks like a cheap sticker.
- The price is 50% or more below the average market price for a similar specification.
- The supplier is unable or unwilling to provide a Certificate of Conformance from the OEM.
- The apron feels unusually light for its stated lead equivalency.
- The supplier is not listed as an official partner on the OEM's website.
Lead Apron accessories & consumables in Nigeria
The most essential accessories, which should be considered mandatory, are thyroid shields (collars), leaded eyewear, radiation-attenuating gloves for interventionalists, and mobile or wall-mounted storage racks. These items are not optional extras; they are integral components of a comprehensive radiation safety program. Thyroid shields protect the highly sensitive thyroid gland, and leaded glasses protect the eye lenses from radiation that can cause cataracts. It is always more cost-effective and efficient to procure these accessories as a bundle with your main apron order. A proper storage rack is the single most important accessory for maximizing the lifespan of your aprons.
- Bundle with the main unit:
- Thyroid Shield: Every apron user must have a dedicated, properly fitting thyroid collar.
- Apron & Glove Rack: A one-time investment that can double the life of your aprons.
- Leaded Glasses: Essential for staff working in fluoroscopy, cath labs, and interventional radiology.
- Mobile Scatter Shield: A crucial tool for protecting other staff (e.g., anaesthetists) in an operating theatre during C-arm procedures.
Lead Apron Storage and Maintenance Requirements
Lead aprons require no power but have strict storage and maintenance requirements to ensure their protective integrity. They must be stored by hanging them on specially designed, wall-mounted or mobile racks that support their weight without causing stress. Aprons must never be folded, creased, or dumped in a pile. Folding creates sharp angles that will crack the internal lead-vinyl sheets, creating "hot spots" where radiation can pass through freely. For maintenance, the outer surface should be regularly wiped down with a mild detergent or an approved disinfectant wipe, as per the manufacturer's instructions, to maintain hygiene and infection control.
- Storage readiness checks:
- Is there a designated, accessible wall space near the procedure room for an apron rack?
- Is the chosen rack robust enough to hold the weight and number of aprons required?
- Have all staff members been formally trained that folding an apron is strictly prohibited?
- Is there a logbook in place to record the date of purchase and annual inspection for each apron?
Lead Apron compliance in Nigeria
The primary compliance requirement for all radiation protection equipment in Nigeria is to meet the standards and regulations set by the Nigerian Nuclear Regulatory Authority (NNRA). The NNRA mandates that all facilities using ionizing radiation must have a comprehensive radiation protection program, which includes providing appropriate and certified PPE for all exposed personnel. During an NNRA audit, inspectors will check your inventory of lead aprons, verify they are in good condition, and review your records of periodic inspection. Maintaining a detailed log for each apron—including its purchase date, inspection results (both visual and fluoroscopic), and eventual disposal date—is a critical compliance activity.
- Compliance dossier items:
- The original purchase invoice for every lead apron and shield.
- The manufacturer's Certificate of Conformance for each model.
- An up-to-date inventory log of all radiation protection PPE.
- A signed and dated annual inspection log for each apron, detailing the results of visual and fluoroscopic tests.
- Records of staff training on the proper use, care, and storage of lead aprons.
financing & leasing for Lead Aprons & Shields in Nigeria
For large-scale purchases, such as outfitting a new hospital wing, a cath lab, or an entire radiology department, financing options are available. These are typically structured through equipment leasing companies or can be bundled into a larger facility loan from a commercial bank. Franance can facilitate financing for bulk orders of lead aprons and shields exceeding NGN 5 million. For smaller orders of just a few aprons, facilities are expected to use their operational budgets. A typical financing arrangement for a bulk order might involve a 20-30% down payment with the balance spread over 12, 18, or 24 months.
- Finance questions to ask lenders:
- What is the minimum order value (in NGN) that qualifies for financing?
- What are the current interest rates and the available repayment tenures (e.g., 12, 24 months)?
- Is a down payment required, and if so, what percentage?
- What documentation (e.g., CAC documents, bank statements) is needed for the application?
- How long does the credit approval process typically take?
Lead Apron total cost of ownership (TCO) in Nigeria
The total cost of ownership (TCO) of a lead apron over its typical 5-year lifespan goes beyond the initial purchase price. It includes the cost of a proper storage rack and factors in the replacement cost of aprons that fail due to improper care. For example, a NGN 200,000 lightweight apron, when stored correctly on a NGN 150,000 5-apron rack (costing NGN 30,000 per apron slot), has a 5-year TCO of NGN 230,000, or NGN 46,000 per year. However, if that same NGN 200,000 apron is folded and cracks within two years, its TCO effectively doubles to NGN 100,000 per year. Investing in storage and training provides the best return and lowest long-term cost.
- TCO levers to manage:
- Invest in Storage Racks: This is the single most effective way to extend apron life and lower TCO.
- Mandatory Staff Training: A 30-minute training session on proper handling can save millions in replacement costs over time.
- Implement Annual Inspections: Catching a single failing apron prevents radiation exposure and demonstrates regulatory compliance.
- Choose Durable Outer Fabrics: A more robust outer material resists tears and damage, protecting the inner core for longer.
Lead Aprons & Shields for hospitals, clinics & NGOs in Nigeria
Tertiary/Teaching Hospital Lead Aprons & Shields
Tertiary hospitals require a comprehensive inventory of radiation protection equipment, including high-protection (0.5mm Pb), lightweight, wrap-around aprons for staff in interventional radiology, cardiology, and operating theatres. They also need a large stock of standard frontal aprons for general radiology and fluoroscopy rooms, patient protection shields (gonadal and ovarian), and multiple large mobile shields on wheels for use in theatres, ICUs, and for bedside procedures.
Private Clinic/Diagnostics Lead Aprons & Shields
A private diagnostic centre primarily needs several high-quality, standard frontal aprons with 0.5mm Pb equivalency for its radiographers. Investing in lightweight composite models is a smart choice for high-throughput clinics, as it reduces staff fatigue and improves workflow. Additionally, a set of patient aprons and at least one thyroid shield per radiographer are essential.
NGO/Mobile Lead Aprons & Shields
NGOs operating mobile X-ray or screening units need lead aprons that are both lightweight and extremely durable to withstand the rigours of transport and frequent handling. A lightweight composite frontal apron is ideal. Portability, ease of cleaning, and a durable outer fabric are the most critical specifications for this use case.
Emergency/Theatre/ICU Lead Aprons & Shields
For procedures involving C-arms in operating theatres, emergency rooms, and ICUs, wrap-around aprons are non-negotiable. They are essential for protecting staff from the high levels of scattered radiation that come from all directions. A large, mobile, height-adjustable lead shield is also a critical piece of equipment to shield other personnel in the room, such as anaesthetists and nurses, who are not directly involved in the imaging process.
