Description 520-525
226Ra, 232Th, their decay products 222Rn, 220Rn and 40K significantly contribute to the mean dose from natural background
radiation. This study reports the concentration of radionuclides in Naturally Occurring Radioactive Materials (NORMS) and
Technologically Enhanced Naturally Occurring Radioactive Materials (TENORMS) of the Shivalik region of Punjab and
Himachal Pradesh. The activity of radionuclides 226Ra, 232Th and 40K in different NORMS (soil, sand, rocks) and
TENORMS (tiles, marble, cement) were calculated by Gamma spectrometry method using an HPGe detector. Radon mass
exhalation and thoron surface exhalation rates were also determined using a Smart RnDuo monitor for the above samples.
From the results, it could be concluded that the radon mass exhalation rate and radium activity were obtained to be
maximum for tile no. 2 and minimum for white marble samples. Similarly, the thoron surface exhalation rate and thorium
activity occurred maximum in tile no. 2 and minimum for safedi. The radium equivalent activity (Raea), gamma activity
concentration index (I), internal hazard index (Hint) and external hazard index (Hext) were computed using appropriate
relations. The values range between 5.858 to 188.944, 0.0403 to 1.377, 0.028 to 0.615 and 0.015 to 0.510 having mean
values of 107.256, 0.685, 0.325, and 0.256, respectively.
