- The current investigation aims to survey levels of natural radioactivity in soil samples gathered from farming and floriculture area to assess environmental radioactivity and radiological wellbeing risk using sodium iodide NaI(TI) gamma-ray spectrometry in Adami Tullu, Shoa, Ethiopia. The outcomes were contrasted and one another and with worldwide standard soil samples. The mean radionuclide concentrations (238U, 232Th, and 40K) in the farming soil samples were 31.39 ± 0.02, 9.43 ± 0.02, and 49.5 ± 0.06 Bqkg/1, and in the floriculture soil samples were 80.69 ± 0.056, 12.9 ± 0.016, and 28.79 ± 0.078 Bqkg/1. The annual effective dose in the farming and floriculture land was lower than the world's methods approval. The absorbed dose rate noticeable all-around at one meter over the ground was gone between 10.4 to 45.5nGyh-1, with a mean of 21.4nGyh/1 in the farming soil samples while it went from 5.87 to 63.67 nGyh/1 with a mean estimation of 43.69 nGyh/1 in the floriculture soil samples. The estimation of the external and internal hazard index was gone from 0.065 to 0.52, with a mean of 0.22 and 0.036 to 0.725, with a mean of 0.42 individually. This worth is underneath as far as possible. Accordingly, the investigation region is safe for nearby local community health.
