Zusammenfassung: | To provide a radiation detection device capable of effectively discriminating between noise and an X-ray signal.SOLUTION: A radiation detection device includes: a detector which detects radiation; a first differential filter which differentiates an output signal of the detector into a first pulse signal; a second differential filter which has a larger time constant than the first differential filter, and differentiates the output signal of detector into a second pulse signal; and a noise detection part which detects noise based upon a difference between the timing of a peak of the first pulse signal and the timing of a peak of the second pulse signal.SELECTED DRAWING: Figure 1
【課題】ノイズとX線信号を効果的に判別することができる放射線検出装置を提供する。【解決手段】放射線検出装置は、放射線を検出する検出器と、検出器の出力信号を微分して第1パルス信号に変換する第1微分フィルターと、第1微分フィルターよりも大きい時定数を有し、検出器の出力信号を微分して第2パルス信号に変換する第2微分フィルターと、第1パルス信号のピークのタイミングと第2パルス信号のピークのタイミングの差に基づいて、ノイズを検知するノイズ検知部と、を含む。【選択図】図1 |
