Abstract  

An observation of signals of acoustic emission induced by tritium decay is reported. The equipment consisting of PZT detectors, preamplifiers, low-cut filters and computer evaluation was used in this study as a differential system. The result shows that the two types of clear signals of acoustic emission are induced by tritium decay. They seem to be related to some radiation effects due to tritium irradiation, and not to acoustic waves during tritium decay events.

Abstract  

The decrepitation results of mineral baryte BaSO4 (Rudňany, Slovakia) of various quality obtained by completed Acoustic Emission (AE)-TG-DTA measurements are presented in this paper. The overall effect of decrepitation ability of major component BaSO4 is not hindered by accompanying mineral siderite FeCO3. This fact confirms decrepitation study of pure minerals by the thermovacuum impulse method, too.
