Abstract
The activity concentrations of primordial radio nuclides (226Ra, 232Th and 40K)have been determined for the brick samples of Jalandhar city of Punjab using HPGe detector based on high resolution gamma spectrometry system. The average activity concentration values of 226Ra, 232Th and 40K from the studied samples are 21.38 Bq kg-1, 25.03 Bq kg-1 and 333.08 Bq kg-1 respectively. The average value of radium equivalent activity (Raeq) for studied brick samples is 80.48 Bq kg-1 which is less than the safe limit 370 Bq kg-1 recommended by Organization for Economic Cooperation and Development (OECD) equivalent to external gamma dose of 1.5 mSvyr-1.
