Radioactive material detection equipment, radiation source position visualization system, and radioactive material detection method

摘要

The radioactive material detection device 2 for detecting a radioactive substance that emits γ-rays and characteristic X-rays that exists in a specific direction Y, and the radiation detecting device 26 for detecting and stopping the radiation incident, the radiation detected by shielding radiation with a shielding container 25 are not allowed to reach use element 26 and the collimator 21, the radiation detecting element 26 detects stop characteristic X-rays coming from the radioactive substance present in the specific direction Y, and from the radioactive substance is the thickness for transmitting the γ-rays arriving, thickness between portion 23 of the hole 22 and the hole 22 of the shielded container 25 and the collimator 21, a characteristic X-ray of the radiation coming from a direction other than the specific direction Y The shielded, and the thickness for transmitting the γ-rays of the radiation coming from a direction other than the specific direction Y. This makes it possible to provide weight exceptionally light, and sufficient performance can be obtained radioactive material detection devices, radiation source position visualization system, and a radioactive material detection method.
