(Received on: April 20, 2016) ABSTRACT Though there is no enough information about radioactivity in Bhola district of Bangladesh due to lack of measurement, geographical position and natural resources of this area are in favour of radioactivity. For this reason, concentration of radionuclides in 21 soil samples have been studied and evaluated. Soil samples were collected from 21 locations of Bhola district. Experimental results were obtained by using a High Purity Germanium (HPGe) Detector and the radioactive standard sources supplied by IAEA were used to determine the efficiency. The measuring time of all samples is 5000 seconds. Keywords: HPGe detector, soil, Radionuclides, 40K, 226Ra, 232Th. 1. INTRODUCTION In our daily life we come across both natural as well as manmade sources of radiation. The natural radioactivity present in soil and rocks whereas man-made sources are nuclear installation, radio nuclides, electronic devices and radiation sources used in industry. Although radionuclides are just a mare material of environment it reminds us the use in medical science, nuclear power plant, industry as well as the horrible day of Hiroshima & Nagasaki.
