A comparative study for indoor radon measurements between CR-39 and Kodak LR115-II detectors

الملخص EN

Because of an increasing interest of radon monitoring in dwelling environments, we investigate radon gas concentrations in dwelling of selected regions of Basrah Governorate.

In the comparative study between LR115-II and CR-39, measurable radon concentrations and relative efficiencies were used in thisinvestigation.

The CR-39 detector was used in cup technique, while the LR115 detector is used as a bare mode.

It is found that LR115 detector is more efficiency than CR-39 in the detection of alpha particle decay of radon, thoron gases and their progenies.

The average indoor radon gas concentration in the target area was found to be 94.2 Bq / m3measured by LR115 and 18.61 Bq / m3 measured by CR-39.

Further, the values of concentrations measured by the two detectors were correlated very well.
