Abstract Gamma irradiation of non-linear resistances shows a pronounced effect on their characteristics. Force-dependent resistances made of polymer materials exhibit high sensitivity to low gamma-doses down to kilorads. In the case of voltage- and light-dependent resistances, the samples have proved to be resistant to gamma-rays, although they lose their main features at high doses (140 Mrad). On the other hand, for temperature-dependent resistances, no permanent damage is determined after exposure to 200 Mrad, while their resistance decreases as a function of the temperature rise due to gamma exposure. Proposals of using such a property in calorimetry, in the field of gamma dosimetry, are given, tested and proved to be satisfactory.
