The X-ray container cargo inspection facility is extensively implemented with the key objective to counter international terrorism and illicit smuggling of the contraband items via the ports. However, activation products are generated from photoneutron capture reactions in the high-energy X-ray container cargo inspection facility. The activation products release inherent delayed radiations which occupational workers are exposed to. In this study, the activation products are estimated using Monte Carlo method and radiation safety of the facility in terms of occupational dose is reviewed.
X射线集装箱货物检查设施被广泛应用,其主要目的是打击通过港口的国际恐怖主义和违禁物品的非法走私活动。然而,在高能X射线集装箱货物检查设施中,光中子俘获反应会产生活化产物。活化产物会释放出职业工作人员会接触到的固有延迟辐射。在本研究中,使用蒙特卡罗方法估算活化产物,并评估该设施在职业剂量方面的辐射安全性。
