Abstract

The study assessed natural radioactivity in Rohtak and Jind districts, Haryana, India. Concentrations of radionuclides in soil and building materials were measured using gamma-ray spectroscopy. The "Canister Technique" was employed to estimate radon mass exhalation and surface exhalation rates. Results showed low radiation doses from soil radioactivity, with activity concentrations ranging from 3.7 to 51.7 Bq/kg for radium, 7.3 to 96 Bq/kg for thorium, and 52.2 to 585 Bq/kg for potassium. The findings also calculated radium equivalent activity, annual effective dose rate, hazard indices, and excess life time cancer risk. This research highlights the importance of understanding natural radioactivity for assessing environmental radiation exposure. [ABSTRACT FROM AUTHOR]

Abstract

Radon (222Rn) and its decay products are the major source of the inhalation dose received by humans due to natural radioactivity. This environmental radioactivity could lead to significant potential risk for living beings as it includes harmful radionuclides. The present work deals with assessment of annual effective dose rates due to indoor radon and thoron in some of the dwellings of Punjab. The equivalent dose rate to lungs (H) due to indoor radon has also been estimated. The indoor radon concentration varies from 18.3Bq m-3 to 122.2Bq m-3 with average value of 63.86Bq m-3. The thoron concentration varies from 23.3 to 172.2Bq m-3 with average value of 89.45Bq m-3. The average values of annual effective dose due to radon and thoron are 1.847 mSv and 2.25 mSv respectively. The higher values of thoron may be due to the higher amount of Thorium (232Th) present as compared to the Radium (226Ra). Equivalent dose rate to lungs varies from 14.64 to 97.8 nSv with average value of 51.15 nSv. The mean value of the inhalation dose from 222Rn and 220Rn in the study area is less than the world’s average mean inhalation dose for 222Rn and 220Rn. Therefore, the health hazards related to radiation are expected to be negligible in the studied area. [ABSTRACT FROM AUTHOR]
