Abstract
We had designed and made the cylindrical ionization chamber which operated above 5 mR/h. Using commercial electrometer, we investigated the characterictic of charge collection in the ion chamber. The active volume was 190.4㎤ and overall length and diameter in the chamber was 15.5cm, 5.22cm, respectively. The chamber had three electrodes(inner, central, wall electrode). And background current was 8.39
조사선량율 5mR/h 이상에서 동작하는 원통형 전리함을 설계ㆍ제작하고 상용의 전류계를 이용하여 전하수집 특성을 조사하였다. 전리함은 전체 길이 15.5cm, 직경 5.22cm인 원통형이고 활성체적은 190.4㎤이다. 전리함의 전극은 벽면, 중심축 및 보호전극으로 구성하고, 이들을 동심축상에 배치하여 바탕전류가 8.39
