| description | To provide a radiation monitor with which it is possible to confirm from a distance easily at low cost whether or not it is operating normally.SOLUTION: A radiation monitor 10 includes a radiation emitting element 1 that emits photons in accordance with incident radiation. An alpha ray emitting material 2 emits an alpha ray and causes it to enter a radiation detection unit 10. An optical fiber 20 transmits the photons emitted by the radiation emitting element 1. A light detection unit 30 detects photons transmitted by the optical fiber 20. A measurement unit 40 measures the count rate of photons detected by the light detection unit 30. An analysis device 50 finds the dose rate of radiation on the basis of the count rate measured by the measurement device 40, and diagnoses whether or not a radiation monitor 100 is operating normally.SELECTED DRAWING: Figure 1
【課題】正常に動作しているか否かを離れた場所から簡易で安価に確認することが可能な放射線モニタを提供する。【解決手段】放射線検出部１０は、入射された放射線に応じて光子を放出する放射線発光素子１を有する。アルファ線放出物質２は、アルファ線を放出して放射線検出部１０に入射させる。光ファイバ２０は、放射線発光素子１にて放出された光子を伝送する。光検出部３０は、光ファイバ２０にて伝送された光子を検出する。測定装置４０は、光検出部３０にて検出された光子の計数率を測定する。解析装置５０は、測定装置４０にて測定された計数率に基づいて、放射線の線量率を求めるとともに、放射線モニタ１００が正常に動作しているか否かを診断する。【選択図】図１ |
