Abstract

A dry and wet wipe test for radioisotope leakage checking was conducted by fixing the radioisotope $^{14}C$ to the glass surface and used for observing the transfer factor and surface shape of the test paper through wipe test. The dry wipe test showed that transfer factor in the tissue paper was twice as high as in the paper filter, and the wet wipe test showed that transfer factor in the paper filter paper was three times higher than the tissue paper. Although paper filters are general choice for leakage checking, it has been shown that tissue paper can be an alternative in the dry wipe test.

유리 표면에 방사성동위원소 $^{14}C$를 고착시키고 문지름 시험을 통해 시험용지별 전이 인자와 표면 형상을 관찰하여 방사성동위원소 누설 점검을 위한 건식 및 습식 문지름 시험법을 연구하였다. 건식 문지름 시험법은 티슈 용지가 종이 필터를 대체 가능할 정도로 2배 높은 전이 인자를 보였고, 습식 문지름 시험법은 종이 필터 용지가 티슈 용지에 비하여 3배 높은 전이 인자를 보였다. 일반적으로 누설 점검을 위해 종이 필터를 사용하고 있지만 건식 문지름 시험법에서 티슈 용지가 대안이 될 수 있음을 보였다.
