Risk assessment from the exposure of natural gamma radiation in the lesser Garhwal Himalayan part, India
Abstract
Health issues due to exposure to natural radiation are a serious concern around the globe as it can damage cell DNA through direct or indirect processes. The present study aims to measure the indoor and outdoor gamma dose rates in different locations of the foothills of Garhwal Himalaya, Uttarakhand India. The average outdoor and indoor gamma dose rate were found 0.15 µSv/h and 0.17 µSv/h. The total annual effective dose equivalent (AEDE) and lifetime effective dose (LED) were found with the average value of 399.03 µSv/y and 25.94 mSv, respectively. Total AEDE was observed to be less than the global population-weighted average.
