This study examines the concentrations of radon, radium, and uranium, along with the annual effective dose and excess lifetime cancer risk due to ingestion of radon in vegetable and fruit samples collected randomly from eleven sites in the Ranya district, Iraq. The solid state nuclear track detector CR-39 was used to monitor radon levels and their progeny. The findings demonstrate that the average concentrations of radon, radium, and uranium in vegetable and fruit samples were 91.05 Bq m, 0.26 Bq kg, and 0.06 ppm, respectively. These results were lower than the global average recommended by ICRP and UNSCEAR. Additionally, the average values of annual effective dose and excess lifetime cancer risk were 0.02 µSv y and 0.08 × 10, respectively. These results comply with internationally recommended safe levels for human consumption. Further research is recommended to evaluate the transfer of radionuclides from soil to edible crops.
本研究检测了伊拉克拉尼亚地区11个地点随机采集的蔬菜和水果样本中氡、镭和铀的浓度，以及因摄入氡而导致的年有效剂量和终生额外癌症风险。使用固态核径迹探测器CR - 39监测氡水平及其子体。研究结果表明，蔬菜和水果样本中氡、镭和铀的平均浓度分别为91.05贝可/立方米、0.26贝可/千克和0.06 ppm。这些结果低于国际辐射防护委员会（ICRP）和联合国原子辐射效应科学委员会（UNSCEAR）建议的全球平均水平。此外，年有效剂量和终生额外癌症风险的平均值分别为0.02微希沃特/年和0.08×10。这些结果符合国际推荐的人类消费安全水平。建议进一步开展研究，以评估放射性核素从土壤向可食用作物的转移情况。
