Radioactivity Natural Environmental Radiation in Middle of Iraq Governorates

Entesser F.Salman* Mohsin Kadhim Muttelab, Jwad K.Manii

In this study 145 sites were modeled for the purpose samples of studying the activity concentrations of naturally occurring 40K, 238U, and 232Th radionuclides and its effect on the population of the selected areas within the study area the probability cancer risk is the main objective of the study absorbed gamma dose rate (DR), annual effective dose, gamma annual gonadal dose (AGDE). The activity concentration 238U, 232Th and 40K radionuclides are within the ranges The concentrations of uranium in the studied area extend (37.091 ± 3.634 to 0.081 ± 0.0008) Bq/kg in soil of Babylon, from (27.913 ± 0.871 to 0.027 ± 0.023) Bq/kg in soil of Najaf, from (109.940 ± 1.730   to 2.478 ± 0.259) Bq/kg in rocks of Najaf, from (37.363 ± 0.700 to 0.190 ± 0.023) Bq/kg in Qadissiya finally from (37.962 ± 0.962 to 0.027 ± 0.233) Bq/kg in soil of Karbala in the area of study,  The correlations between both the probability of cancer with 238U equal  to (0.3724) it means that the relationship of uranium to cancer is weak, but with 232 Th  and 40K, annual effective dose in air, γ-radiation index, radiation greater than this positive correlation in study area. The correlation between annual gonadal dose (AGDE) and absorbed gamma dose rate RA (nGyh−1) outdoor AGDE and ADRA (nGyh−1) indoor indicating that most areas of study pose a clear risk to individuals in these areas.
