Description 945-954
Elevated levels of primordial radionuclides (238U/ 232Th- decay series and 40 K) are the foremost source of higher
background radiations. Natural radioactive elements may prove precariously radioactive in some situations. So, it is essential
to quantify the natural levels of radioactivity in the soil to figure out how much the population is exposed to, what the health
risks are, and have a starting point for figuring out how radioactivity in the environment will change due to human activities.
In this study natural radioactivity in the soil of different residential areas of Fatehabad and Hisar districts in Haryana, India
has been quantified. HPGe gamma spectrometry has been used to quantify the activity of 226Ra, 232Th, and 40K in the soil of
the area under investigation. The respective activity concentration of 226Ra, 232Th, and 40K ranged 32 to 53 Bq kg−1, 23 to 41
Bq kg−1, and 402 to 610 Bq kg−1. The activity equivalent to radium only (Raeq), the air absorbed dose rate (AAD), the
effective dose equivalent rate(AEDEC), the gonadal dose equivalent rate (AGDE), the external risk index, the internal risk
index, the index for gamma level, cancer risk for an average lifetime, etc. were calculated and compared with the
international standards. Each sample of soil had lesser radium equivalent activities than the permissible limit, i.e., 370 Bq
kg-1primarily set by the Organisation for Economic Co-operation and Development (OECD), and the effective dose
equivalent was below the safe limit of 1.0 mSv y-1. Organ-specific dose values are pretty considerable but not in the danger
zone. The Clark value refuses the probability of finding any uranium ore. This study indicates that the area being studied is a
place with low background radiation exposure from radionuclides.
