This study was conducted to establish baseline radioactivity levels around the Jordan Research and Training Reactor (JRTR) pre-commissioning. Activity of artificial and natural radionuclides in plant leaves and cow’s milk samples was measured using gamma-ray spectroscopy. The annual effective internal dose for adults due to intake of milk and milk products was estimated to be 27.8–33.5 µSv which is lower than worldwide average. These results provide a benchmark of the baseline activity levels in the vicinity of the JRTR reactor before commissioning for future reference.

约旦研究和培训反应堆周围植物叶子和牛奶样品的预调试基线活动水平

进行这项研究是为了在约旦研究和训练反应堆 (JRTR) 预调试周围建立基线放射性水平。使用伽马射线光谱法测量植物叶子和牛奶样品中人工和天然放射性核素的活性。由于摄入牛奶和奶制品，成年人的年有效内剂量估计为 27.8-33.5 µSv，低于世界平均水平。这些结果为 JRTR 反应堆附近的基线活动水平提供了一个基准，供未来参考。
