摘要
本文介绍了我国放射性物质运输概况(除台湾省外)。目前,全国放射性物质货包的年运输最约10万件,总放射性活度为1.8PBq,运输的放射性同位素主要是^(131)I、^(32)P 和^(198)Au 等。承运人员的年剂量当量是相当低的,一般小于5mSv。由于十分重视放射性物质的安全运输,所以没有发生过严重事故。文中还讨论了放射性物质运输中的防护问题。
This paper describes an outline of transport of radioactivematerial in China(except for Taiwan and Hong Kong).At present,theannual freight packages of radioactive material is some 100000 pieces.Total activity of them is about 1.8 PBq.The radioisotopes are mainly^(131)I,^(82)p and ^(198)Au.The available results show that individual doses totransport workers are rather low.The annual dose equivalent is less than5 mSv/a.Much attention has been paid to safe transport of radioactivematerial.Hence,accidents with serious radiation hazard have never occu-rred.A working group is working out Chinese regulations for safe trans-port of radioactive material on the basis of IAEA safety series No.6(1985).
