|Title:||Natural radioactivity levels in granite regions of Karnataka State|
Narasimha, K N Prakash
|Abstract:||The activities of <sup>226</sup>Ra, <sup>232</sup>Th and <sup>40</sup>K and natural radiation levels have been measured at granite regions of Karnataka State, India using HPGe detector and scintillometer. In granite region <sup>232</sup>Th activity is high compared to <sup>226</sup>Ra. The data shows that the activities of <sup>226</sup>Ra, <sup>232</sup>Th and <sup>40</sup>K and ambient γ-radiation level were found to be high in comparison to global and Indian average<sup>1</sup>.|
