Modeling response of radon track detectors with solid absorbers as radiators

Recently, a new radon monitor, based on the combination of plastic radon absorber/radiator and an alpha-track detector, has been proposed. In this report a theoretical model of its response is described. The modeling is performed for two widely used track detectors: CR-39 and Kodak Pathe LR-115 type II. Theoretical estimates of the response for various designs of such monitors are obtained and comparison with available experimental data is made. The results demonstrate the feasibility of this approach for practical applications.
