目的通过实际测量调查,了解某生物实验室放射性同位素标记的放射性污染水平。方法使用Iden-tifinder-N型X、γ剂量率仪、BH3206型表面沾污仪进行工作场所监测。结果部分工作场所环境γ外照射明显高于环境本底水平,β放射性表面污染属于正常本底水平。结论加强对同位素工作场所辐射安全管理,降低工作场所环境放射性水平。并提出相应的辐射防护。
Objective To understand the level of radioactive contamination of radiolabelled radioactive isotopes in a biological laboratory through surveys of actual measurements. Methods Workplace monitoring was performed using the Iden-tifinder-N X, γ dose rate meter and the BH3206 Surface Contamination Meter. Results Some of the workplace environment γ external exposure was significantly higher than the ambient background level, β radioactive surface contamination is normal background level. Conclusion Strengthening radiation safety management in isotope workplace and reducing environmental radioactivity in the workplace. And put forward the corresponding radiation protection.
