Study of the radiological doses and hazard indices in soil samples from Karbala city, Iraq

Original · EN

The radiological doses and hazard indices of natural radionuclides ²³⁸U,²³²Th and ⁴⁰ K in soil samples from Kerbala city were evaluated using gamma-ray spectroscopy system using NaI(Tl) "1.5× 2" detector in low-background with 24 hour. The average values of absorbed gamma-ray dose rate, annual effective dose equivalent and annual gonadal dose equivalent were found to be 90.83±2.00 nGy/h, 111.89±2.46 μSv/y and 640.85±15.44 μSv/y respectively. The average values of gamma representative level index and external hazard index resulting from natural radionuclides for all samples in the study area were 1.43±0.031 and 0.53±0.011 respectively. The obtained results in current work were compared with other results for different countries.
