【摘要】：目的通过对临床核医学诊疗中辐射剂量的研究,探索核医疗安全管理和辐射防护的具体方法,以保障患者、医疗工作人员以及广大社会群众的身体健康。方法针对最为常见的核医疗方法 131I治疗,选取68例接受131I治疗的患者,并将他们随机分为两组,每组分别由一名医师和两名护士负责治疗工作,一组采用常规治疗防护措施进行治疗,一组采用综合治疗防护措施,并记录两组患者服用131I后的有效剂量和医护人员1年所受的总辐射剂量,然后进行对比分析。结果经过1年的治疗之后,采用常规治疗防护措施的患者受辐射剂量为(59.63±0.56)mSv,医生和护士受辐射剂量为(4.692±0.056)mSv;采用综合治疗防护措施的患者受辐射剂量为(50.21±0.69)mSv,医生和护士受辐射剂量为(1.216±0.037)mSv。结论患者接受131I治疗所受到的辐射量大于公众照射年剂量限值,但比职业照射的年剂量限值低,但通过综合的防护措施,可以有效降低131I治疗对患者和医护人员的辐射剂量,能够保障接受临床核医学诊疗的患者和医护人员的安全健康。
[Abstract]:Objective to explore the specific methods of nuclear medical safety management and radiation protection through the study of radiation dose in clinical nuclear medicine diagnosis and treatment in order to protect patients. Methods 68 patients who received 131i treatment were randomly divided into two groups. Each group was treated by a physician and two nurses, one group was treated with routine treatment and the other group was treated with comprehensive treatment and protection measures. The effective dose after 131I and the total radiation dose received by medical staff for one year were recorded and compared. The results were compared after one year of treatment. The dose of radiation was 59.63 卤0.56mSvand that of doctors and nurses was 4.692 卤0.056mSv. The radiation dose was 50.21 卤0.69 mSv. The dose of radiation to doctors and nurses was 1.216 卤0.037 mSv.Conclusion the dose of 131I is higher than the annual dose limit of public irradiation. But it is lower than the annual dose limit of occupational exposure, but the radiation dose of 131I treatment can be reduced effectively by comprehensive protective measures. To ensure the safety and health of patients and medical staff receiving clinical nuclear medicine diagnosis and treatment.
