The research is oriented towards studying the detection of alpha radiation using solid trace detectors, with consideration of detector response functions, calibration coefficients, energy window and critical detection angles. The research also includes the examination of the emanation factor and exhalation rate of radon, as well as various methods of measuring the concentration of radon and its progeny in air and water. The research is also aimed at measuring the specific activities of natural and artificial radionuclides in the environment, with the aim of examining the factors that influence their distribution, bioavailability and risks to human health. The research combines experimental methods, theoretical models and computer simulations.
