dc.description.abstractThe 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.id
