The study aimed to measure indoor concentrations of radon, thoron, and their progeny in populated areas across seven locations in Muzaffarnagar using dosimeters, DTPS, and DRPS. The data collected over one year across four quarters revealed significant variability in concentration between locations and seasons. The highest average concentration of radon was found in Charthawal from November to January (92.3 Bq/m³), while the highest average concentration of thoron was observed in Mansoorpur from August to October (84.9 Bq/m³). The average concentration of radon progeny was highest in Rohana from November to January (24.7 Bq/m³), while the average concentration of thoron progeny was highest in Tirupadi from August to October (2.9 Bq/m³). Significant variations were observed in the concentration of radon, thoron, and their progeny between locations, which can be due to geological differences, building materials, and ventilation rates. The data also revealed seasonal variation, with November to January having the highest average concentrations of radon, thoron, and their progeny. The total effective dose of radon + EERC varied considerably across locations, with Tirupadi having the highest total effective dose of 0.89 mSv/year, and Muzaffarnagar having the lowest total effective dose of 0.62 mSv/year and similarly for thoron + EETC having the highest of 0.42 mSv/ year. the lowest of 0.07 mSv/ year in Rohana.

The study aimed to measure indoor concentrations of radon, thoron, and their progeny in populated areas across seven locations in Muzaffarnagar using dosimeters, DTPS, and DRPS. The data collected over one year across four quarters revealed significant variability in concentration between locations and seasons. The highest average concentration of radon was found in Charthawal from November to January (92.3 Bq/m³), while the highest average concentration of thoron was observed in Mansoorpur from August to October (84.9 Bq/m³). The average concentration of radon progeny was highest in Rohana from November to January (24.7 Bq/m³), while the average concentration of thoron progeny was highest in Tirupadi from August to October (2.9 Bq/m³). Significant variations were observed in the concentration of radon, thoron, and their progeny between locations, which can be due to geological differences, building materials, and ventilation rates. The data also revealed seasonal variation, with November to January having the highest average concentrations of radon, thoron, and their progeny. The total effective dose of radon + EERC varied considerably across locations, with Tirupadi having the highest total effective dose of 0.89 mSv/year, and Muzaffarnagar having the lowest total effective dose of 0.62 mSv/year and similarly for thoron + EETC having the highest of 0.42 mSv/ year. the lowest of 0.07 mSv/ year in Rohana.
