摘　　要：目的分析1例职业性放射性肿瘤诊断过程中遇到的问题和处理方法。方法在剂量估算时选取剂量转换方式,将个人剂量当量、皮肤吸收剂量、文献检测数据均转换为红骨髓吸收剂量,并计算PC 95%可信上限。结果劳动者放射致癌病因概率PC 95%可信上限为66.38%,可判断为放射性肿瘤;剂量估算过程存在个人剂量数据缺失;现行剂量估算标准无床边拍片和CT工作类型且剂量转公式不够完善。结论在职业性放射性肿瘤判断过程中,剂量估算结果存在一定不确定性,亟需制订并颁布符合目前放射诊疗技术和设备进展、更具操作性的相关剂量估算标准。Objective To analyze the problems and solutions in the diagnosis of a patient with occupational radiogenic neoplasms.Methods The dose conversion method was selected in dose estimation.Personal dose equivalent,skin absorbed dose,and reported detection data were converted into red bone marrow absorbed dose.The upper 95%confidence limit of the probability of causation(PC 95%)was calculated.Results The PC 95%of cancer due to radiation in the worker was 66.38%,which suggested occupational radiogenic neoplasms.Personal dose data were missing in dose estimation.The current dose estimation standard lacked bedside radiography and CT operation type,and the dose conversion formula was not perfect.Conclusion In the judgment of occupational radiogenic neoplasms,the estimated dose showed uncertainty.There is an urgent need to formulate and promulgate dose estimation standards that are operational and in line with the current development of radiological diagnosis and treatment technology and equipment.
