Effect of natural radionuclide's in the environment along the Jwalamukhi thrust of Himachal Pradesh, North West Himalayas, India.

This research paper is devoted to measure the activity contents of natural radionuclide, like, radium (²²⁶Ra), thorium (²³²Th) and potassium (⁴⁰K) in the soil gathered along the Jwalamukhi thrust of Himachal Pradesh, North Western Himalayas, India. NaI(Tl) Scintillator detector was utilized for the estimation of activity content. The activity concentration of ²²⁶Ra, ²³²Th and ⁴⁰K for some of the soil samples have been observed to be above the global normal mean values. The outcomes acquired for indoor and outdoor effective dosage are well below the normal international and national proposed results. The determined values of external hazard (H_ex) for studied locations are less than unity, therefore; samples assembled from these regions are safe from a health hazard point of view and can be utilized as a construction purposes without producing any radio-logical hazard to human beings. The average estimations of radium equivalent activity were found to be within the limits suggested by Organization for Economic Cooperation and Development (OECD). Radon (²²²Rn) and thoron (²²⁰Rn) exhalation rates have also been calculated and discussed. [ABSTRACT FROM AUTHOR]
