THE COMPACT DISC AS A RETROSPECTIVE RADON DETECTOR: PERFORMANCE OF THE METHODOLOGY

Recently, a method for long-term 222 Rn measurements was proposed that combines the radon absorption ability of some polycarbonates, like Makrofol, with their track-etch properties. The method is independent of any particular 222 Rn progeny behavior and the very first evaluation of this approach showed that its range of sensitivity covers practically the entire range of indoor 222 Rn-concentrations. This method has been extensively studied in the period 2001 ‐ 2007. In this report we comprehend the performance of the method as demonstrated in the laboratory studies.
