# Abstract:

This analysis discusses the unattenuated thermal radiation which comes directly from the fireball onto a receiver oriented perpendicular to the radius vector out to this point. Primary emphasis is placed on the derivation of an equation similar to equation 3 of Ref. 1 Chapman, R. M. and M. H. Seavey.

Secret for bursts intermediate to air and ground bursts and which reduces to the correct value at these two extremes. Presented also is a table of theoretical ground burst gamma values which are used for computing the energy reflected off the terrain. Author
