What Is Radiation Safety, Shielding & Dosimetry In Sierra Leone?
Radiation safety, shielding, and dosimetry in Sierra Leone are critical components of ensuring the responsible and safe use of ionizing radiation within the country's healthcare system and other applications. This encompasses the principles, practices, and technologies employed to minimize the risks associated with radiation exposure to patients, healthcare workers, and the general public. Its importance stems from the dual nature of radiation: while it offers invaluable diagnostic and therapeutic benefits in medicine, uncontrolled or excessive exposure can lead to detrimental health effects, including increased cancer risk. The scope within local healthcare in Sierra Leone involves the implementation of safety protocols for diagnostic imaging (X-rays, CT scans), radiotherapy, and nuclear medicine procedures. This includes proper equipment maintenance, radiation protection measures for staff and patients (e.g., lead aprons, shielding), accurate monitoring of radiation doses received by individuals, and emergency preparedness for radiation incidents.
