Device for sampling radioactive material and analytical method of radioactive material
Device for sampling radioactive material and analytical method of radioactive material
PROBLEM TO BE SOLVED: To efficiently perform the analysis of a radioactive material locally distributed.SOLUTION: This radioactive material sampling device 1 includes: a radiation detection unit 10; and a radioactive material sampling unit 20. These units are fixed to a ROV100 via a frame 110. For this reason, the radiation detection unit 10 and the radioactive material sampling unit 20 are integrated each other and move on the sea bottom B together with the ROV100. The radiation detection unit 10 recognizes the presence or absence of a radioactive material piece in the sea bottom B, and when the radioactive material pieces are recognized, the soil around the periphery thereof is sampled by a radioactive material sampling unit 20. A radioactive material sampling device control unit recognizes which detection intensity of the radiation detector in each of the measuring heads is the highest, and recognizes a region inner position of the radioactive material piece.SELECTED DRAWING: Figure 1

Abstract
PROBLEM TO BE SOLVED: To efficiently perform the analysis of a radioactive material locally distributed.SOLUTION: This radioactive material sampling device 1 includes: a radiation detection unit 10; and a radioactive material sampling unit 20. These units are fixed to a ROV100 via a frame 110. For this reason, the radiation detection unit 10 and the radioactive material sampling unit 20 are integrated each other and move on the sea bottom B together with the ROV100. The radiation detection unit 10 recognizes the presence or absence of a radioactive material piece in the sea bottom B, and when the radioactive material pieces are recognized, the soil around the periphery thereof is sampled by a radioactive material sampling unit 20. A radioactive material sampling device control unit recognizes which detection intensity of the radiation detector in each of the measuring heads is the highest, and recognizes a region inner position of the radioactive material piece.SELECTED DRAWING: Figure 1
