Abstract
The kinetics of Hg(CNO)2 decomposition in the following four regimes: thermolysis, radiolysis at T < 336 K, radiolysis at T > 336 K, and thermolysis of the preirradiated compound, were studied in order to determine the main characteristics of the joint effect of radiation and temperature. It was found that preirradiation, as well as the simultaneous action of heat and radiation, eliminated the induction period of thermolysis, increased the rate of thermolysis by an order of magnitude, and decreased the thermolysis onset temperature. It was concluded that irradiation induces complex radiation defects, acting as sites at which parallel–consecutive steps of the thermal process occur both during and after irradiation. The rate-limiting step depends on temperature. Three temperature regions were distinguished (T < T therm, T therm < T < 370 K, and T > 370 K), and the effective values of E act were found.
