Program documents record any authorizations and accreditations that allow or regulate the exposure of individuals to radiation (e.g., radioactive material licenses from the U.S. Nuclear Regulatory Commission or U.S. Department of Defense authorizations to possess radioactive commodities). They also include all documentation necessary to define the radiation protection program that safeguards the health and well-being of workers. Among these records one would find records of training programs, dosimetry procedures, environmental monitoring plans, and documentation of efforts to keep exposures ALARA.
Individual records document relevant data on each individual exposed to radiation as part of his or her occupational duties. These include items such as exposure categories for individuals (e.g., managers who receive minimal radiation doses versus technicians who receive larger doses). Also of interest are individual dose records (internal and external), training records, and details of any overexposures, as well as age, sex, and other identification data that allow individuals to be followed in epidemiologic studies. Records should follow the individual as he or she changes employer or work situation. It also is useful to record individual work history and conditions. This allows the calculation of accumulated internal dose and, when necessary, verification of external dosimetry information after an exposure occurs.
Workplace records document activities and conditions in the environs of the individual exposures. These records include data on radiation levels in various areas, descriptions of restricted areas, descriptions of activities that require personnel exposures (work permits), records of movements of radioactive materials, data on the availability and condition of protective equipment, and documentation of accidents and incidents.
Environmental records document radiologically significant characteristics of the environment and include results of measurements of the radionuclide contents of the air, ground, and water. These records can be valuable in reconstructing the doses received by personnel who may have been exposed during a release of radioactivity.
Instrumentation records are maintained to document the availability, calibration, maintenance, and capability of radiation detection and measurement devices. These records are used for quality control purposes to ensure the accuracy of radiological measurements.
Regulations require that Nuclear Regulatory Commission licensees advise each worker annually of his or her total radiation dose for that year and the total career dose. If a former worker requests dose information, a licensee must furnish a report of that worker's exposure within 30 days of the time of the request or within 30 days after the exposure has been determined by the licensee (CFR, 1998b).
