Stability of dielectric properties of aluminum under gamma-quantum irradiation

Abstract

In this work was to reveal the effects of gamma-quantum irradiation on the microstructure and electrophysical characteristics of aluminum. The effects of gamma irradiation with a radionuclide source of cesium-137 isotope on the properties of aluminum were studied. The maximum absorbed doses were approximately 108 rads. Aluminum plates with a thickness of 6 mm and an area of 5 cm2 were utilized during the experiments. The main challenge in obtaining reliable, adequate automated adaptation of the gamma spectrometer under conditions of change in a certain range of characteristics of the water environment (such as, for example, temperature and pressure) is the task of obtaining reliable, high-quality and reliable measurements. The paper presents the results of testing and adjustment of the complex of autonomous automated calibration of 137Cs gamma-spectrometer. The processes occurring during gamma-quantum irradiation of aluminum and their influence on dielectric properties of the material were studied. The results obtained indicate that when aluminum is irradiated with a dose of 108 rad, only a slight change in its dielectric permittivity is observed.
