dc.description.abstractNatural radionuclides of plants food are the main sources of internal radiation exposure in human. Mount Sinabung is one of the active volcanoes which in the past 10 years it has been always shown a continuous activity until to date. The study was carried out to evaluate the natural radionuclides concentration in soil and some food grown in Karo District. The soil and food crops sample collected from Karo District were analysed by means of Gamma Spectroscopy for radionuclides 226Ra, 232Th and 40K. The concentration radioactivities in food crops were follows 226Ra and 232Th could not detected, 40K = 124,81 ± 3,59 Bq/Kg. Transfer factors are the most important parameters required for mathematical modeling used for environmental impact assessment of radioactive contamination in the environment. The result showed that the transfer factor for 226Ra and 232Th were not found because very low concentration and 40K was 0,27. The annual internal dose received by domestic population living in District Karo due to the consumption of the foodstuff was 0,0103 mSv/year which is very much lower than annual dose limit of 1 mSv for general public.id
