The exposure of human population to natural radioactivity has become an important issue. Natural radioactivity is hazardous to health and is usually determined from 226Ra, 232Th and 40K. These radionuclides emit gamma radiations which on inhalation and ingestion lead to irradiation on human body. The aim of present work was to study the activity concentration and radium equivalent due to 226Ra, 232Th and 40K radionuclides. This study was carried out in soil samples of Shaheed Bhagat Singh District of Punjab, India using gamma ray detector NaI(Tl). Activity concentration of natural radionuclides 226Ra, 232Th and 40K in soil of Shaheed Bhagat Singh District of Punjab varies from 28 Bq/kg to 38 Bq/kg, from 38.2 Bq/kg to 55.4 Bq/kg and from 201 Bq/kg to 376 Bq/kg with average values of 32.2 Bq/kg, 48.8 Bq/kg and 324.3 Bq/kg respectively. Radium equivalent from these radionuclides is found to vary from 96.7 Bq/kg to 139.6 Bq/kg with average value of 124.7 Bq/kg which is less than the safe limit of 370Bq/kg recommended by OECD (Organization for Economic Cooperation and Development).
