Abstract
The quality correction factor for used beam and qualities is strongly required for clinical dosimetry by TRS-398 protocol of IAEA. In this study the quality correction factors for a commercial plane-parallel ionization chamber in high energy electron beams were calculated by Monte Carlo code(DOSRZnrc/EGSnrc). In comparison of quality correction factor, the difference between this study and TRS-398 were within 1% in 5-20 MeV. In case of 4MeV the difference was 1.9%. As an independent method of determination of quality correction factor this study can be applied to evaluate values in the protocol or calculate the factor for a new chamber.
국제원자력기구의 TRS-398 측정 프로토콜을 임상에 적용하기 위해서는 사용하는 빔과 전리함에 대한 선질 보정인자가 필요하다. 본 연구에서는 몬테칼로 계산코드(DOSRZnrc/EGSnrc)를 사용하여 상용의 평판형전리함에 대한 고에너지 전자선(
