RADIOACTIVITY CONCENTRATION MEASUREMENT DEVICE AND SORTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a radioactivity concentration measurement device capable of obtaining a reliable radioactivity concentration of a measuring object.SOLUTION: A radioactivity concentration measurement device 1 includes: a carrier unit 6 in which a belt 4 of a measuring conveyor 5 moves in a first direction A1 and conveys a measuring object M in the first direction A1; a return unit 7 in which the belt 4 moves in a second direction A2; and a radioactivity concentration measuring instrument 12 for obtaining a measurement/detection value indicating the radioactivity concentration of the measuring object M being conveyed in the first direction A1. The radioactivity concentration measuring instrument 12 is installed in a measuring instrument installation unit 11 between the belt 4 in the carrier unit 6 and the belt 4 in the return unit 7.SELECTED DRAWING: Figure 2
