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.
