某新建核医学病房放射防护检测与评价分析

目的根据国家相关标准，对某医院新建核医学病房放射防护情况检测，并对检测过程发现的问题及检测结果进行评价分析，提出确保安全运行的放射防护建议。方法采用FD-3013B智能γ辐射仪及451P型加压电离室巡测仪测量核医学工作场所的环境放射防护水平，LB124型表面污染测量仪进行表面污染检测。结果该核医学科及周围环境辐射最大值为1．01μSv／h，各个工作场所中表面污染的最大值为2．14Bq／cm^2，职业人员全年有效剂量的最大值为2．02mSv。结论该核医学病房布局合理，辐射防护检测结果符合相关标准要求，但放射防护管理存在不完善的地方，经过整改后，在正常条件下能有效地控制职业病危害；为保护工作人员和公众的身体健康，应进一步完善相关防护措施，并使用专用防护用具。

Radiological Protection Testing and Analysis of Nuclear Medicine Department in A Hospital

Objective To analyze the test results of radiological protection level of nuclear medicine department in a hospital according to the national standard and put forward optimized suggestion for radiologieal protection. Methods Using ＂FD-3013B＂ intelligent T radiometer and ＂451P＂ radiation survey meter to measure the level of environmental radiological protection in nuclear medicine workplace, and Using ＂LB124＂ surface contamination meter to conduct detection of surface contamination. Results The radiation maximum of the department and the surroundings was 1.01μ Sv/h, the maximum of surface contamination was 2.14 Bq/cm^2, the annually maximum effective dose among professional staff was 2.02mSv. Conclusion The site of the nuclearmedicine department is appropriate, and the layout is rational. The monitoring results for the radio protection and surface contamination in workplace accord with national standards. However, there are inadequacies in the management of radiological protection. To protect the health of the staff and the public, protective should be further improved.
