摘要：
PURPOSE: A directional multi-channel beta probe is provided to accurately check the position of a radiation source by removing a gamma noise that is a position resolution obstacle when a beta ray is detected.CONSTITUTION: An organic scintillator (10) is formed with an optical fiber type to easily detect a beta ray in comparison with a gamma ray. The organic scintillator emits a visible ray by reacting on the beta ray. A silicon photomultiplier (20) is connected to the organic scintillator and converts the visible ray from the organic scintillator to an electric signal. A reflector (30) is formed on the organic scintillator to transmit the visible ray to an optical sensor without a loss. The lateral side of the organic scintillator is shielded with lead to remove a gamma noise and an external visible ray.COPYRIGHT KIPO 2013지향성 다채널 베타 프로브에 관한 발명이다. 상기 지향성 다채널 베타 프로브는, 실효원자번호가 작고 감마선 검출보다 베타선 검출에 용이하며, 광섬유 형태로 제작된 유기섬광체 및 상기 유기섬광체와 연결되며, 상기 유기섬광체에서 발생된 가시광선을 전기적 신호로 변환하는 실리콘 광증배소자(SiPM)를 포함한다.
