Two classes of people are envisaged:

  • (i) persons exposed to ionizing radiation in the course of the pursuance of their duties,

  • (ii) members of the general public.

In Table 10.1.2[link], the maximum primary dose (MPD) for those in class (i) and class (ii) is tabulated. SI units are shown in bold type, and the earlier units are shown in parentheses in light type.

Planned special exposures are permissible in emergency circumstances provided that in any single exposure twice the annual dose limit is not exceeded, and in a lifetime five times the limit.

Also, to allow for the different biological effectiveness of different types of radiation, the quality factor listed in Table 10.1.3[link] is applied to determine the dose.
