The research is oriented to the investigation of the detection of ionizing radiation using solid state nuclear track detectors. A computer program was developed according to model based on the diffusion, deposition and decay of radon and its progeny in diffusion chamber. The focus of research was to investigate spatial distribution of alpha particle tracks produced by radon and its progeny on CR-39 detector surface. The research also include measurements of natural and artificial radionuclides in the environment, measurements of radon concentrations, examination of correlations between radon concentrations and 226Ra concentrations in the surrounding soil, and studies of the transfer of radionuclides from soil to plants. The plan also includes a comparison of different methods for determining the emanation fraction of radon, based on gamma spectrometry and fitting experimental data obtained by the RAD7 device
