Abstract

The concentrations of natural radionuclides 226Ra, 232Th and 40K in four types of chemical fertilizers, the soil samples and Mount Sinabung Volcanic Ash have been measured by gamma spectrometry with a high purity germanium (HpGe) detector. The mean activity concentration of 226Ra, 232Th and 40K measured for Agricultural Soils are 27,69 Bq/kg, 57,31 Bq/kg, 294,04 Bq/kg (Jeraya Villages) and 34,79 Bq/kg, 84,16 Bq/kg, 175,50 Bq/kg (Tiga Panah Villlages), respectively. Then, activity concentration of 226Ra, 232Th and 40K measured for different fertilizer samples were relatively high for 40K at 3406,605 Bq/kg and relatively low for 226Ra and 232Th at 26,85 Bq/kg and 14,56 Bq/kg, respectively. Activity concentration of 226Ra, 232Th and 40K for Volcanic ash are 12,56 Bq/kg, 33,62 Bq/kg and 519,32 Bq/kg, respectively. The radiological hazards of the radium equivalent activity (Raeq), absorbed dose and annual effective are also evaluated in this study.
