SPECIFIC RADIOACTIVITY INSPECTION SYSTEM OF FISH

Japanese Patent JP2014173991

A

PROBLEM TO BE SOLVED: To provide a specific radioactivity inspection system of a fish in which a whole individual fish can be continuously and efficiently inspected, and capable of sorting the fish for each specific radioactivity with sufficient accuracy.SOLUTION: A specific radioactivity inspection system 1 of a fish according to the present invention includes: a weight measuring table 3 for performing individual identification and also performing weight measurement of a plurality of fishes; a belt conveyer 4 for conveying the plurality of fishes in a row in a predetermined conveying direction A; a plurality of radiation detectors 7 positioned below the plurality of fishes to be conveyed and arranged side by side in the conveying direction A; a pair of radiation shielding walls 16, 17 positioned on the right and left sides of the plurality of fishes subjected to radiation detection and provided along the conveying direction A; radiation shielding members 11, 14 provided to surround the underside and both left and right sides of the radiation detector 7; a control part 6 for individually calculating the specific radioactivity of the fish based on individual identification information, a weight measuring result, and a radiation detection result; and a sorter 5 for sorting the fish based on the calculation result of the specific radioactivity.
