The thermal decomposition of AgMnO/sub 4/, pre-irradiated in BEPO and in a Co/sup 60/ hot spot, has been investigated in the temperature range 100 to 125 C. The results are similar to those for irradiated KMnO/sub 4/ and the mechanism proposed for the latter is again suggested. The activation energy for the migration of point defects over the induction pericd is 1.09 ev. The decomposition of unirradiated and irradiated crystals differ in that the latter undergo physical disintegration over the acceleratory period. X-ray studies immediately prior to disintegration show strain and fragmentation in the irradiated crystal. An explanation is advanced for the changes produced in the p/ t plots with increased dosage, and a fixed decomporsition temperature. (auth)
