Since the creation of the universe, natural radioactivity has been an integral part of our environment and all living things are living and have to live in a sea of radiations. The natural radioactivity is caused by γ-radiation originating from the uranium, thorium series and K40. In the present study the activities of Ra226, Th232, and K40 have been measured in the lignite samples of the of Nichahoma Lignite belt of the Kashmir valley, India using NaI(Tl) Gamma ray spectrometer. The measured specific activity concentration of Ra226 and Th232 was found to be higher than the Indian coal mines, the data presented by Germany, USA, and UK. The radiation Hazard indices are also calculated and reported.
