Radioactivity monitoring device
专利汇可以提供Radioactivity monitoring device专利检索，专利查询，专利分析的服务。并且PURPOSE: To enable completely continuous monitoring with high resolving power and measure radioactivity not lower than a prescribed value, by feeding gas containing a radioactive substance, at a prescribed period to the entire circumference of an annular radioactive substance adsorption collector.
CONSTITUTION: An annular collector 20, which comprises a paper filter 17, a wire net 18, an adsorbent 16 such as activated charcoal for adsorbing iodine, etc., is rotated at a constant speed by a position controller 9, a motor 3, etc. so that gas containing a radioactive substance is fed to the entire circumference of the annular collector 20 from the gas feed hole of a lead shield 6 through a pump 13. As a result, intermittent collection is not performed but completely continuous collection is effected through a detector 7 in another lead shield 5 to enable continuous radioactivity monitoring with high resolving power. According to this constitution, radioactivity not lower than a prescribed level can be always measured.
