摘要： PROBLEM TO BE SOLVED: To improve workability, while reducing workers' exposure doses, when conducting a radiolucence test for a tubular member in a plant. SOLUTION: After a support means and a guide pipe are mounted inside the tubular member, beforehand, the radiolucence test for a newly peripheral welded part is conducted by inserting a radiation source for the test into the guide pipe after the completion of the newly peripheral welding on the tubular member. This measure eliminates the need for workers who conduct the radiolucence test to remain inside the tubular member over a long time, which can not only reduce workers' exposure doses, but can also significantly improve workability in the radiolucence test.

摘要翻译：要解决的问题：为了提高可加工性，同时减少工人的暴露剂量，当对植物中的管状构件进行放射性测试时。
解决方案：预先将支撑装置和导管安装在管状构件内部之后，新外围焊接部件的放射性试验通过在试验完成之后将用于试验的辐射源插入导管中来进行在管状部件上进行新的周边焊接。该措施消除了对长时间放置在管状部件内进行放射性测试的工人的需要，这不仅可以减少工人的暴露剂量，而且可以显着提高放射性能测试中的可操作性。版权所有（C）2010，JPO＆INPIT
