Experimental study of the response of radon track detectors with solid absorbers as radiators

摘要

A new concept for passive radon monitors-"radon film badges" has been recently proposed. It uses plastic radiators of high radon absorption ability, coupled with external solid state nuclear track detector (SSNTD). First experiments and theoretical modeling revealed a remarkable potential for practical applications. In this report we present results of a dedicated experiment in which detectors were coupled with different absorbers and placed in a variety of different easy-to-carry packages. The results confirmed that radon can freely diffuse in the packages. The response of the monitors with different absorbers was determined and a good agreement with the theoretical model was found. This strengthen the basis for further research and development of this new methodology.
