摘要

Ionizing radiation emitted from radionuclides is present everywhere in the environment. It is the main source of health hazards to the general public. The present study elaborates on the analysis of primordial radionuclides in the collected soil samples from the Main Central Thrust (MCT) region of Uttarakhand Himalaya in a grid pattern. The naturally occurring radionuclides radium (226Ra), thorium (232Th) and potassium (40K) were analyzed using a thallium-doped sodium iodide detector-based gamma-ray spectrometer. The activity concentrations of 226Ra, 232Th and 40K were found to vary from 9.82 ± 2.35 to 39.17 ± 5.50 Bq kg−1 (arithmetic mean 15.76 Bq kg−1), 15.09 ± 6.93 to 32.90 ± 7.80 Bq kg−1 (arithmetic mean 21.66 Bq kg−1), and 165.71 ± 43 to 417.16 ± 61.73 Bq kg−1 (arithmetic mean 320.30 Bq kg−1) respectively. The spatial distribution and radiation hazards of primordial radionuclides are discussed in the paper.
