The amount of material released and respirable will be equivalent to the TNT

equivalent mass of the explosive, except where the TNT equivalent mass

exceeds the total mass of the material at risk, in which case the amount of

material released and respirable will be the total mass of the material at risk.

High explosive detonations involving nuclear weapons and associated

assemblies will use a value for the fraction of material released and respirable

equal to 2E-1. Additional discussion of airborne release resulting from such

detonations can be found in DOE-HDBK-3010-94, Section 4.1 (Reference 5).
