Description

The activity concentration of natural radionuclides and 222Rn (Radon) exhalation rate in soil samples were determined using NaI Scintillation detector and Scintillation Radon Monitor. Soil samples were collected from different geological formations of the same area. The average value of 226Ra (Radium) equivalent activity in soil samples of the studied area was 124.9 Bq kg-1. 226Ra equivalent activities was calculated for the analyzed samples to assess the radiation hazards arising due to the use of these soil samples in the construction of dwellings. The 222Rn exhalation rate in the studied area was varied from 6.9 ± 0.2 mBq Kg-1 h-1 to 33.2 ± 2 mBq Kg-1. A positive correlation was obtained between the Ra (Radium) and 222Rn exhalation rate. The overall average annual effective dose in the studied is lower than the world recommended value of 1.0 mSva-1. (author)
