Evaluation of the natural radioactivity of samples of some types of field crops in different areas of Tikrit, Iraq.

Abstract

This study aims to assess the concentrations of natural radionuclides activity (226Ra,232Th and 40K) and calculate a number of radiation risk indicators in some types of field crops in different areas of Tikrit City - Salah Al-Din Governorate - Iraq. The measurement was carried out using a gamma ray spectroscopy connected with a scintillation detector crystallized with thallium-activated sodium iodide NaI(TI). The results were that t 0……he mean concentrations of elements (226Ra,232Th and 40K) wer (6.79±0.33 1Bq/Kg,10.79 ± 0.640 Bq/Kg, 133.34± 5.895 Bq/Kg), respectively. And the radiation risk indicators were less than the international permissible and the recommended average, so that the samples under study are safe and suitable for human and animal consumption.
