ISSUES ON RADIATION SAFETY SUPERVISION OF RADIOACTIVE MATERIAL TRANSPORTATION IN CHINA

摘要

China has been attaching greater attention to the safety supervision on the transport of radioactive material packages, one key part of which is the radiation monitoring to the radioactive material packages and vehicles. Issues on the radiation monitoring and safety supervision of radioactive material packages transportation discussed include: (1)Determination of proper monitoring location close to package surface; (2)Neutron radiation monitoring; (3)Choosing proper detectors for complicate radiation field monitoring; (4)Optimization of surface contamination monitoring. The requirement in Chinese standard and solution on above issues during practice are also given.
