radioactive material detection device, radiation source position visualization system, and radioactive material detection method

摘要

The radioactive material that emits -ray and the characteristic X-ray to be present in a particular direction Y the radioactive material detection device 2 for detecting a radiation detection element 26 for detecting and stopping the radiation incident radiation is shielded with the radiation is not allowed to reach the detection device 26 shielding container 25 and the collimator 21, the radiation detecting use device 26 detects stop characteristic X-rays coming from a radioactive substance present in the specific direction Y, and a thickness for transmitting the rays coming from the radioactive substance, the shielding container 25 and the collimator 21 thickness between portion 23 of the hole 22 and the hole 22 of the shielding characteristic X-ray of the radiation coming from a direction other than the specific direction Y, and, among the radiation coming from a direction other than the specific direction Y is the thickness that transmits the -ray. Thus, it is 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 methods.
