目的检测甘肃省某医院核医学科ECT中心工作场所的辐射水平,并评价检测结果和放射防护设施与措施是否符合国家有关法律、法规和标准,确保职业病危害因素得到有效控制,保障工作人员、患者和公众的安全与健康。方法依据国家相关标准对ECT中心放射性表面污染及机房周围泄漏辐射进行检测,对医院设置的放射防护措施、建立的规章制度及其落实情况进行现场核查,评估ECT中心在正常运行状态下对工作人员及公众的影响。结果 ECT中心放射性表面污染水平最高值为0.42 Bq/cm2,机房周围各检测点泄漏辐射值均小于0.1μSv/h;该ECT中心正常工作状态下的放射性表面污染水平及泄漏电离辐射符合国家标准的要求,医院设立的放射防护措施有效,制定的规章制度基本得到落实。结论该ECT中心在正常运行的情况下不会对工作人员和周围公众的健康造成有害影响。
Objective To detect the radiation level in the workplace of ECT Center of Nuclear Medicine of a hospital in Gansu province and evaluate whether the test results and radiological protection facilities and measures are in conformity with relevant laws, regulations and standards of the state to ensure that occupational hazards are effectively controlled and that staff, patients And public safety and health. Methods According to the relevant national standards, the radioactive surface contamination of ECT center and leakage radiation around the engine room were detected. The radiation protection measures, established rules and regulations and the implementation status of the ECT center were verified on site, and the ECT center was evaluated on the condition of normal operation And the public’s influence. Results The highest level of radioactive surface contamination in ECT center was 0.42 Bq / cm 2, and the radiation leakage at each detection point around the engine room was less than 0.1μSv / h. The radioactive surface contamination level and leakage ionizing radiation under normal working conditions of ECT center were in line with national standards Requirements, the hospital set up radiation protection measures effective, the development of the rules and regulations have been basically implemented. Conclusion The ECT Center will not adversely affect the health of staff and surrounding public in normal operation.
