COMPARISON OF RADON CONCENTRATION MEASURED BY SHORT-TERM (ACTIVE) AND LONG-TERM (PASSIVE) METHOD

Measuring of radon concentration in an indoor space in most cases is carried out by passive method by means of track detectors (CR – 39) with the period of exposure of six or twelve months. On the other hand, active method is less used, semiconductor detectors (Rad 7) with a direct reading of radon concentration and period of measurement of 7 days. The aim of this work is to compare the results of passive and active method in order to determine Pearson correlation coefficient between these two methods.
