A calorimetric method for studying radiation-chemical processes in condensed media

摘要

A calorimetric method is developed to study the thermokinetics of radiation-chemical processes (RCPs). The samples under study are heated by gamma radiation absorbed in the adiabatic mode. The developed method allows the minimum level of reliably detected thermal effects of RCPs to be decreased by more than an order of magnitude as compared with conventional calorimetric methods. The calorimetric system is also virtually free from the time lag typical of the majority of dynamic calorimeters. These advantages allow the kinetics of reactions with rather low radiation-chemical yields to be studied immediately during irradiation.
