Abstract

PURPOSE:To reduce irradiation on an operator and to perform a high-precise sampling and radiation detection, by a method wherein a dust sampler unit is mounted in a spot which is low in back ground and is easy to maintain and inspect. CONSTITUTION:A holder stocker 36 is located adjacent to a sampling and detecting part 10 for radioactive dust, and a plurality of filter paper holders 42 whereto filter papers for radiactive dust are individually attached are stored in lamination. A lamination holder group in the stocker 36 is moved vertically with an elevating shaft 50 moved vertically. A holder extracting mechanism 58 extracts a given filter paper holder 42 from the lamination holder group to feed it to the sampling and detecting part 10 where a sampling and detection for the radioactive dust are performed. The filter paper holder 42 is then restored to the original position.
