Which documentation is essential for monitoring personnel radiation exposure?

The correct choice emphasizes the importance of personnel dosimetry records in monitoring radiation exposure among individuals working in environments where they may be exposed to ionizing radiation. These records are critical because they provide a detailed account of the amount of radiation each worker has been exposed to over a specific period.

Personnel dosimetry involves the use of devices such as thermoluminescent dosimeters (TLDs), film badges, or electronic dosimeters, which measure the dose of radiation that staff members receive. By keeping accurate dosimetry records, organizations can ensure compliance with safety regulations, assess potential health risks to employees, and implement necessary changes to reduce exposure. Furthermore, these records are vital for establishing trends and making informed decisions regarding personnel safety and operational practices within radiation-using facilities.

In contrast, operational records may include data on equipment and activities, but they do not specifically track radiation exposure levels for individuals. Safety audits evaluate the overall safety practices and compliance within an organization but do not provide detailed personal exposure information. Environmental impact assessments focus on the effects of operations on the surrounding environment and community rather than on individual radiation exposure, making them less relevant in this context. Thus, personnel dosimetry records stand as the fundamental documentation required for effectively monitoring radiation exposure
