Summary:PROBLEM TO BE SOLVED: To improve a measurement accuracy by lengthening a retention time of a radioactive material, even if a flow rate of a flowing fluid is quick in a sample chamber. SOLUTION: In a shield chamber 21, the sample chamber 24 and a radiation detector 25 are mounted. The sampler for the radiation detection measures a radioactivity of the radioactive material containing in the flowing fluid continuously flowing in the sample chamber 24 by the radiation detector 25. A hollow fiber film filter 26 constituted with a hollow fiber film which separates the radioactive material from the fluid is mounted in the sample chamber 24. COPYRIGHT: (C)2005,JPO&NCIPI
