Abstract |
|
|
| The current study aims to measure and calculate the concentrations of natural radioactive elements (226Ra, 232Th, 40K) in samples of fertilized soil and non-fertilized soil in different areas of Tikrit, the administrative center of Salah al-Din Governorate. The measurement was carried out using a gamma-ray spectroscopy system connected with a scintillation detector crystallized by NaI (TI). The results were obtained, and the average concentrations of natural radioactive elements (226Ra, 232Th, 40K) were (11.24±0.455 Bq.〖Kg〗^(-1) ,23.65±1.305 Bq.〖Kg〗^(-1) ,291.52±9.814 Bq.〖Kg〗^(-1)) on the Respectively in fertilized soil samples. The average concentrations of natural radioactive elements in un fertilized soil samples amounted to (5.28±0.216 Bq.〖Kg〗^(-1),11.82±0.617 Bq.〖Kg〗^(-1),154.17±5.253 Bq.Kg-1 ), respectively. Thus, all the results in the samples under study that we obtained are less than the global average recommended by the International Atomic Energy Committees at the United Nations, and accordingly, the areas under study are safe and do not pose a source of danger to the environment. |
