Abstract
A device for measuring large-area radioactive surface contamination can simultaneously obtain a plurality of detection values. The measurement device includes a frame body having a plurality of holes; a mover that is connected to, and moves, the frame body; and a plurality of radiation detectors that rest in the plurality of holes. The detectors detect one or more of: alpha rays, beta rays, or gamma rays. The location and level of radioactive contamination are accurately identified according to a comparison of the detection values of the plurality of radiation detectors.
Claims14
A large-area radioactive surface contamination measurement device, comprising:
- a frame body with a plurality of holes formed;
- a mover connected to the frame body to move the frame body;
- a plurality of radiation detection modules, each seated in the plurality of holes to detect at least one of:
- alpha rays, beta rays, and gamma rays;
- and
- a control unit for calculating a radioactive contamination location and a radioactive contamination level by comparing detection values of the plurality of radiation detection modules with each other;
- wherein each radiation detection module comprises:
- a counter seated in each of the plurality of holes, each counter having at least one horizontally extending seating wing for seating the counter;
- a photomultiplier tube coupled to the counter;
- and
- a channel unit mounted on the photomultiplier tube.
