低コスト化が図られるという効果も得られる。In the filter paper holder according to the present invention, a memory IC for writing and holding measurement points and sample sampling conditions and an antenna coil for reading and responding to data from the memory IC are directly connected to the filter paper holder. Because it is sealed in the holder body, it is smaller and smaller in size and weight than the conventional filter paper holder that mounts a general-purpose IC memory card, and a large number of gas sampler dust collectors for dust monitoring operation in large-scale radiation facilities This has the effect of facilitating handling such as carrying and mounting when the filter paper holder is renewed and replaced, and reduces the storage space. In addition, the filter paper holder, in which the filter paper is inserted without a door, eliminates the need for the hinge and hook structures, thus enabling a more compact and compact configuration and lower cost combined with the reduced number of parts. The effect that the conversion is achieved is also obtained.
