described for application of criteria to limit, whole body dose for
individuals to 0.5 rem per year and to limit exposure of a siutable
sample of the population to 0.17 rem per year is likely to assure that
the gonadal exposure guide will not be exceeded.
Environmental radiation monitoring is a necessary part of
complying with the RPG guidance.
The intensity and frequency of
measurements is to be determined by the need to be able to detect
sharply rising trends and to provide prompt and reliable information
on the effectiveness of control actions.
