The process whereby relatively high energy density, spherical zones of radiation heating may arise from slow pi --meson irradiations is described, and the effects of such microscale hot spots on six explosives (lead azide, lead styphnate, mercury fulminate, RDX, TNT, and PETN) was investigated. No explosions or signs of thermal decomposition were observed with any of the explosives. Analysis of these results by the hot-spot model of explosive initiation and thermal growth was attempted. The conclusions were: that this model can not explain the experimental results observed for RDX, in that it predicts initiation, and that the previous experiments attempting explosive initiation by the microscale thermal effects of ionizing radiation have not investigated those explosives most susceptible to initiation by this mechanism.
