Comparison of LR-115 SSNTD based Integrated sampler with Yu-Guan bronchial dosimeter for measurement of inhalation dose due to radon progeny.
J. Instrum. 14:P010122 (2019)
Estimation of inhalation dose due to radon progeny is important as it is one of the major carcinogens for development of lung cancer. In recent years, Solid State Nuclear Track Detectors (SSNTDs) are widely used for evaluation of radon progeny concentration without measuring the parent radon gas concentration and subsequently deriving it using the assumed equilibrium factor. In the present study, the performance of LR-115 SSNTD based integrated sampler which is used for measurement of radon progeny concentration was studied against the bronchial dosimeter proposed by Yu and Guan. The comparison of inhalation dose measured using both the Integrated sampler and Yu-Guan dosimeter was carried out at three different ventilation rates such as 0.5 h -1 , 4.5 h -1 and 9.5 h -1 and two different relative humidity conditions such as 50% and 90%. It was observed that the doses measured using these two different dosimeters are very similar. An increase in ventilation rate or in relative humidity leads each to a decrease in annual effective dose as measured with both the detectors.
