This report describes the results of the test for sampling characteristics of some personal air samplers which are widely used for estimating the hazard due to inhalation of airborne harmful materials in the nuclear fuel plants and other industrial installations.
The personal air samplers investigated are three kinds, namely, of the trade mark of MSA Monitaire Sampler, UNICO Mighty Mite and Casella MK II.
In order to measure the flow rate of each sampler, a transducer was calibrated by means of other experimental procedure, before the flow rate tests were made. The battery capacity without the load and the maximum load under the constant voltage supply were also studied.
The maximum flaw-rate without the load was about 5l/min in the UNICO, 4l/min in the MSA and 2l/min in the Casella, respectively. The sampling air volume of the UNICO sampler is, however, most decreased by the increase of load, compared with those of the Casella and the MSA samplers.
Some other basic data useful for improving the characteristics of samplers were also obtained.
