Safety Reviews of Transport Container of Radioactive Sources

Some radioactive sources are often used in irradiation industry and radiotherapy, such as co-60, cs-137, i -131, p-32, sm-153, mo-99, sr-90, sr-89 etc. Recently, the amount of radioactive sources transportation is large in china. The safety performance of radioactive material package must meet the requirements of “regulations for the safe transport of radioactive material” (GB11806-2004). According the requirements of GB11806-2004(the requirements of GB11806-2004 are same with the requirements of IAEA SSR6), containers for radioactive sources transport should be demonstrated to be enough safety by test or simulation calculation methods. In this paper,safety reviews of one type of radioactive sources transport container is presented. Finite Element Analysis Method is used to find the drop posture of most several damage. Drop test of one kind of radioactive sources transport package has been conduct, some test results were obtained, such as the stress, acceleration. Both of the simulation results and tests results are used for safety performances reviews of this type of radioactive sources transport container is finally verified meeting the requirements of GB11806-2004. A discussion of how the test and finite element analyses were combined for the safety performance reviews of a type of package is given.
