In the present study, indoor radon and thoron concentrations were assessed using a newly developed pin hole-based twin cup dosimeter with a single-entry face in some areas of Punjab state, India. The equilibrium equivalent concentrations of radon and thoron were estimated directly by using the newly developed progeny (decay products) sensors designed by Bhabha Atomic Research Centre, Mumbai, India. The average radon and thoron concentrations in the study region were found to be 61.6 ± 18.6 Bq/m3 and 68.0 ± 30.8 Bq/m3, respectively, while the average equilibrium equivalent concentrations of radon and thoron were 25.9 ± 7.7 Bq/m3 and 2.2 ± 0.7 Bq/m3, respectively. Calculated average equilibrium factor for radon and thoron was 0.45 and 0.04, respectively, in the present study. The annual inhalation dose that was calculated from the present observed concentrations varied from 1.1 to 4.1 mSv/year with an average value of 2.4 mSv/year, which is well within the reference level of 10mSv/year recommended by International Commission on Radiological Protection. The study shows that thoron is a significant contributor to the inhalation dose, which is about 29% of the total inhalation dose.

An extensive survey to measure natural radioactivity in human environment in Jalandhar district of Punjab was undertaken. Results of measurements of indoor radon/thoron and their progeny concentrations are being presented here. Single-entry, pin-hole dosemeters were used for the measurement of radon/thoron concentrations. Deposition-based direct radon/thoron progeny sensors were used for measurement of progeny concentrations. The results have been analysed on the basis of regional characteristics, type of construction and building material used. The radon concentration was found to vary from 6.64 ± 1.72 Bq/m3 to 47.18 ± 4.43 Bq/m3 with geometric mean value of 17.9 ± 2.91 Bq/m3 while the thoron concentration varies from 7.75 ± 2.54 Bq/m3 to 82.68 ± 8.33 Bq/m3 with geometric mean value of 33.54 ± 5.09 Bq/m3. The geometric mean value of equilibrium factor for indoor radon and thoron was found to be 0.43 and 0.02, respectively. The estimated annual inhalation dose varies from 0.22 mSv to 1.76 mSv with geometric mean value of 0.66 mSv. Correlation of indoor radon and air gamma dose rate was also studied.

Abstract Studies are being conducted for the past few decades in and around the uranium mining sites across the globe to identify environmental nuclear radiation risk to the common public. The area near Dasarlapally village was identified for uranium exploration by the AMDER, Hyderabad. The present study was carried out to measure the indoor radon and thoron activity concentrations in the dwellings of Dasarlapally village. For this purpose different types of dwellings were chosen randomly across the village. The measured annual average concentration of radon and thoron in dwellings were found to be 141 ± 42 and 139 ± 77 Bqm−3, respectively, and the calculated annual effective inhalation dose due to radon was determined to be 3.5 mSv. Seasonal variation and diurnal variation of radon and thoron activity concentration were investigated. The variation of radon and thoron activity concentration in different types of dwellings was also studied, and the variation was found to be statistically insignificant. The uncertainty propagated in the effective inhalation dose due to thoron was discussed.
