7.2.3.3

Radioactive Material Onsite Exposure Determination. In the rare instance

when assessment of exposure to onsite personnel outside the facility is

desired (see discussion in Appendix A, Section A.1.2), the exposure to

the maximally exposed individual at 300 m (984 ft) should be estimated in

a manner consistent with the assumptions used in DOE-STD-1027-92,

Attachment 1, for the calculation of Category 2 radiological thresholds,

but with a dose threshold of 25 rem (0.25 Sv) instead of the 1 rem (0.01

Sv) used in this standard. Equivalently, the Category 2 radiological

thresholds identified in DOE-STD-1027-92 can be used as the basis for

exposure determination, using the following equation.
