| Abstract | ||
| To study the radioactivity for soil of AL-Haidriya city in AL-Najaf AL-Ashraf , Choosing (30) location to take samples from the cityand tow samples were collected from each site, the first from surface soil (0-10) cm , the second depth (20-30) cm , to reach (60) sample and The gamma rays spectral measurements were done for all samples by using Iodide Sodium activated by Thallium NaI(Tl), its dimension 3"× 3". Were found the averageof the quality activity for of uranium 238U , thorium 232Th and potassium 40K, in the studied models (10.00±2.17)Bq/Kg ,(8.73±2.29)Bq/Kg and (66.53±3.72)Bq/Kg, respectively.The average values of the equivalent radium ,The absorbed dose in air ,The effectivedose of annual internal, The effective dose of the annual external,external risk coefficient,internal risk coefficient andthe activity concentration index (Iγ) where(26.42±5.68) Bq/Kg , (12.65±2.57) nGr/h , (0.0620±0.0126) mSv/yr , (0.0154±0.0030) mSv/yr , (0.0729±0.0153) , (0.0983±0.0210) and(0.1944±0.0394)respectively.By comparing the results with worldwide, It was found that the levels of radiation for samples studied within the permissible limits globally | ||
