METHOD FOR SPACECRAFT NUCLEAR POWER PLANT RADIATION PROTECTION DEVICE TESTING Russian patent published in 1997 - IPC

Abstract RU 2073919 C1

FIELD: nuclear energy engineering, measurement technology. SUBSTANCE: object under test processing, namely lithium hydroxide shadow protection device is exposing by penetrating radiation and it resultant radiation is examining. X-ray radiation with energy spectrum 100-200 keV is using and it registration is making synchronously by two collimation detectors using. One of them is placed at direct vision of X-ray source but another is moving along back surface of radiation safety device under investigating. Radiation power doze accumulation is making step-by-step by both detectors simultaneously. Safety thickness of protection device measuring value is comparing with early known nomographic chart calculating for protecting object safety neutron flux standard. Protection device safety resource is calculating by known formula using. EFFECT: more effective method for radiation safety device testing. 1 dwg
