A gamma ray counter capable of measuring a radioactive ray in a broad dose area according to the present invention is characterized in comprising: a body having an accommodation space therein; a radioactive ray detection module which is arranged at an eccentric position with respect to one side from the accommodation space of the body; a first chamber which is formed at a center portion of the radioactive ray detection module; a second chamber which is arranged to be apart from the first chamber and at one side boundary of the radioactive ray detection module; and a third chamber which is arranged to be opposite to the first chamber with the second chamber between them, wherein the third chamber is arranged to be farther from the second chamber than a distance between the first chamber and the second chamber. 본 발명에 따른 넓은 선량 영역의 방사선 측정이 가능한 감마선 계수기는, 내부에 수용 공간을 구비한 몸체; 상기 몸체의 수용 공간 일측으로 편심된 위치에 배치된 방사선 검출 모듈; 상기 방사선 검출 모듈의 중앙부에 형성된 제1챔버; 상기 제1쳄버와 이격되도록 배치되며, 상기 방사선 검출 모듈의 일측 경계에 배치된 제2챔버; 및 상기 제2챔버를 사이에 두고 상기 제1챔버의 맞은 편에 배치되며, 상기 제1챔버와 상기 제2챔버 간 거리보다 상기 제2챔버로부터 더 멀리 이격되도록 배치된 제3챔버;를 포함한 것을 특징으로 한다.
