目的探讨1起工业探伤误照事件的健康危害评价。方法采用剂量仪、热释光(TLD)剂量元件进行现场模拟,估算操作人员可能受照的剂量,结合临床观察与血象检查结果,评价操作人员受照的健康危害情况。结果通过现场模拟和TLD剂量计的数据,推算出可能受照的物理剂量,结合临床血象检查结果,计算操作人员受照随机性效应的概率。结论此次误照事件未对操作人员造成确定性效应,发生随机性效应的概率也较低。
Objective To investigate a health hazard assessment of industrial flaw detection. Methods Dosimetry and thermoluminescence (TLD) dose components were used to carry out on-site simulation to estimate the dose that the operator may be exposed to. Combined with clinical observation and blood test results, the health hazard of operators was evaluated. Results Based on the field simulation and the TLD dosimeter data, the possible dose of physical exposure was calculated, and the probability of operator random effects was calculated based on the results of clinical blood tests. Conclusion The incident did not cause false positive operator certainty effect, the probability of random effects are lower.
