The state or condition of being subject to radiation. External exposure is exposure to radiation from a source outside the body. Internal exposure is exposure to radiation from a source within the body. Graded approach An application of safety requirements that is commensurate with the characteristics of the facilities and activities or the source and with the magnitude and likelihood of the exposures. Health surveillance Medical supervision intended to ensure the initial and continuing fitness of workers for their intended tasks. Incident Any unintended event, including operating errors, equipment failures, initiating events, accident precursors, near misses or other mishaps, or unauthorised act, malicious or the consequences or potential consequences of which are not negligible from the point of view of protection and safety. Ionising radiation For the purposes of radiation protection, radiation capable of producing ion pairs in biological material(s). Justified See ‘Justification’ Justification For a planned exposure situation, the process of determining whether a practice is overall, beneficial, i.e. whether the expected benefits to individuals and to society from introducing or continuing the practice outweigh the harm (including radiation detriment) resulting from the practice. Medical exposure Exposure incurred by patients as part of their own medical or dental diagnosis (diagnostic exposure) or treatment (therapeutic exposure); by persons, other than those occupationally exposed, knowingly, while voluntarily helping in the support and comfort of patients; and by volunteers in a program of biomedical research involving their exposure. Occupational exposure Exposure of workers incurred in the course of work. Occupationally exposed person A worker who is exposed to ionising radiation in the course of work.
