In some special cases, such as a nursing station or outdoor sidewalk, the distance from the barrier to the nearest routinely occupied area may be considerably greater. 3 Occupancy Factors The occupancy factor (T) for an area is defined as the average fraction of time that the maximally exposed individual is present while the x-ray beam is on. Assuming that an x-ray unit is randomly used during the week, the occupancy factor is the fraction of the working hours in the week that a given person would occupy the area, averaged over the year.

In some cases, however, it may be prudent to ignore the preshielding. For example, in cross-table lateral examinations the beam may not always be fully collimated to the patient and cassette. 6. The examples given in Section 5 show computations of barrier requirements with and without preshielding for completeness. 3 30 2 a Since patient attenuation is ignored, potential variations in image-receptor attenuation from different manufacturers is not a significant factor. 2. 1 CONCEPTS AND TERMINOLOGY / 45 appropriate rests with the qualified expert.
