CR-39 detector compared with Kodalpha film type (LR115) in terms of radon concentration

CR-39 detectors and Kodalpha film type (LR115) were compared in terms of radon radiation concentration. Thirteen CR-39 detectors with the same number of Kodalpha film type (LR115) were used in this study. The correlation factor between the radon concentrations, obtained by the two groups of detectors was found to be 0.99. Detector time efficiency (DTE) was calculated for both types of detectors. DTE of Kodalpha film is larger than that of CR-39 detector and this indicates that LR115 is more efficient and sensitive for radon radiation than CR-39 detector.
