Abstract
The activities of the naturally occurring radionuclides 232Th, 226Ra, 40K and 238U of the shore sediments in the South Gondar Zone were determined and used to evaluate radiation hazards in the study spots. The activities of 232Th, 226Ra, 40K and 238U range from 46 to 179, 62 to 140, 125 to 449 and 72-156Bq/kg, with the overall average of 123.07±7.90, 105.34±4.27, 371.38±13.53 and 115.52±4.62Bq/kg, respectively. These were analogous to concentrations of other states in worldwide. We recommend to all the concerned bodies about the environment that the farmers require use the necessary radiation protection method before deploying them for farming (irrigation) activities and preparing for construction. Therefore, accommodating a permanent protection method by talking to the concerning bodies (e.g. Ministry of Agriculture and Ministry of Health) should be taken.
