“…On the other hand, the present results were in disagreement with the conclusions of some investigators [35] who, however, used detectors made of another plastic material. For better and deeper explanation another type of experiment (mainly chemical and checking the interaction at the atomic level) should be accomplished in the future.…”

Radon passive monitors based on solid state nuclear track detectors (SSNTD), especially CR-39, are widely used in radon and thoron studies. They may be subjected to the influence of external factors, like changing of temperature, humidity, and pressure, both before and during the measurement. Evaluation of the exposed detectors involves chemical processing, whose conditions also influence the measurement results. The aim of this study was to check several factors, as to whether they may modify the response of CR-39 detector: concerning the phase before evaluation, storage time, and temperature during storage; and concerning the evaluation procedure, etching time, and pre-etching treatment using hot water and carbon dioxide atmosphere. Two experiments were conducted by irradiation of CR-39 detectors using alpha particles emitted from a mono-energetic 241Am source and exposed in radon atmosphere. Track density dependence of the age of production was found to be statistically not significant. On the other hand, pre-etching treatment using hot water and carbon dioxide with different etching times showed statistically significant effects on track area, track sensitivity, and roundness. It was concluded that there are simple methods to increase performance of nuclear track detectors, and that storage time is not a factor of concern.

Measurements of indoor radon have a critical role in monitoring human health and safety. In this study, measurements of radon in the houses of Bingöl and Mus provinces and in their surrounding villages were performed by using CR-39 nuclear track detectors. Bingöl and Mus Provinces of Turkey have the severe terrestrial climate with hot and dry summers and cold and snowy winters for a long period. Therefore, people who spend much of their time at home have a greater risk for being exposed.
