摘　　要：目的检测自屏蔽回旋加速器的辐射剂量,以保障放射工作人员的安全。方法应用手提便携式辐射测量仪检测加速器室、放化实验室以及靶的拆卸和重装过程中的辐射剂量。结果加速器室、放化实验室以及靶的拆卸和重装过程中的辐射剂量在规定的安全范围之内。结论回旋加速器自屏蔽系统、合成热室、分装防护屏等具有良好的辐射屏蔽效果。Objective To detect the radiation dose of self-shielding cyclotron to ensure the security of radiation workers. Methods Detecting the dose of radiation released by self-shielding cyclotron in cyclotron room, radiochemical laboratory and the teardowning and reinstalling process of target body with a portable radiation measuring instrument. Results The radiation dose in cyclotron room, radiochemical laboratory and the teardowning and reinstalling process of target body is within the security scope. Conclusion The self-shielding system, hot synthesis chamber and safety shield of self- shielding cyclotron have good shielding effect for radiation.
