Radioactive Material Offsite Exposure Determination.

material excluded from the hazardous material inventory, as discussed in

Section 7.2.2 of this document. Facility segmentation (as discussed in

DOE-STD-1027-92) or other means of demonstrating the lack of facility-

wide release potential may be used, as appropriate, to reduce the

inventory for direct comparison with guidelines. In all cases, however,

such reductions should be justified in terms of the unavailability of

common-cause release mechanisms stemming from aircraft impact.

Radioactive Material Offsite Exposure Determination. The exposure to

7.2.3.2

the maximally exposed individual at or beyond the site boundary will be

estimated in terms consistent with the screening guidelines presented in

Source term values will be based upon a bounding release consistent

with the following assumptions:

a. All material in close proximity to high explosives present at the facility

will be assumed to be subjected to the energetics associated with

high explosive detonation.

b. No credit will be taken for mitigation, either passive or active,

including ventilation, fire suppression, building confinement, and

rubble effects.

c. The fraction of radioactive material assumed to be driven airborne

and respirable will be based on Table II, which is derived from DOE-

HDBK-3010-94 and explained in Reference 8.
