Title:
放射能測定装置
Document Type and Number:
Japanese Patent JP6987086
Kind Code:
B2
Abstract:
To provide a radiation measuring device with which it is possible to measure a radioactive intensity distribution in the depth direction of a measurement object with high accuracy.SOLUTION: A radiation detection unit 1, inserted into a concrete piece T, is constituted to be capable of moving in a depth direction Y to the inside of the concrete piece T, and detects radiation at a plurality of detection positions P in the depth direction Y. A response function K of the radiation detection unit 1 is constituted in correspondence to radiation emitted from a radioactive substance 50 in each detection area Re, and a radioactive intensity computation unit 23 performs signal restoration computation using the response function K on wave height distribution M of radiation derived at each detection position P and thereby discriminates the nuclide of the radioactive substance 50 and computes radioactive intensity I in the depth direction Y of the discriminated radioactive substance.SELECTED DRAWING: Figure 1
