Estimation of radon progeny concentration based on track morphological parameters.

As the integrated measurements of radon progeny are essential to its risk assessment, a new method based on the morphological analysis of tracks on CR-39 was established for the discrimination of alpha particles emitted from different progenies. The preliminary experiment confirmed its feasibility and revealed its potential for application in long-term surveys of indoor radon progeny. This new attempt was expected be benefit to the improvement of integrated measurements of radon progeny.
