摘要:
目的 以我国西部地区最大型肿瘤医院放疗中心(四川省肿瘤医院)为代表,对其周边工作环境及工作人员辐射剂量水平进行调查和分析。方法 采用热释光剂量计对在中心工作的医生、护士、技术员、物理师、工程师和T作场所60Co治疗机、医用加速器、后装治疗机、X线模拟定位机、CT、MRI、头部γ刀、医生办公室)与外环境进行为期60d连续的累积剂量监测,并将所得结果和有关部门公布的调查结果进行比较分析。结果 该放疗中心室内工作环境平均剂量约为1.96μC·kg-1·月-1,室外环境剂量为1.6μC·kg-1·月-1。结论 由于该中心25年来严格按照环保和防护部门规范建设,所有机房外、办公区和候诊区的辐射水平均在完全安全范嗣内,无一超标。
Abstract:
Objective To investigate and analyze the radiation dosage around the working environment in radiotherapy centre affiliated to Sichuan cancer hospital in the western China.Methods In 60 days,we have continuously monitored the accumulated dose that absorbed by doctors,nurses,technicians,physicists and engineers,and investigated the working environment 60Co unit,accelerator,after loading unit,X-ray simulator,CT simulator,gamma knife,MRI and doctor’s office)and external environment by using TLD,and compared our results to those released by relevant departments.Results The average dosage in the working environment is 1.96 μC·kg-1·month-1,1.61 μC·kg-1·month-1 in external environment.Conclusion In the past 25 years,the radiotherapy center constructed strictly by the criterions of environment and protection departments required,so the radiation dosage in or outside the radiotherapy center has reached the national standard,which is safe for the staff and patients.Its instatement that the radiotherapy sites constructed by the related laws well accorded with the safety standards regulated.
