一、引言快中子用于辐射育种,在我国已有十多年的历史,取得了可喜的成果。以中子通量来量度照射量已不适应中子辐射育种的需要。为了配合快中子辐射育种及中子治癌和研究中子的生物效应,需要较为准确地测定生物组织快中子的吸收剂量。测定中子吸收剂量的方法很多。但从近几年来举行的几次国际比对情况来看,使用最多
I. INTRODUCTION Fast neutrons are used in radiation breeding and have been in our country for more than ten years and have achieved encouraging results. To measure the amount of neutron flux exposure has not adapted to the needs of neutron radiation breeding. In order to meet the fast neutron breeding and neutron neutron cancer and biological effects of neutron research, the need for more accurate determination of biological tissue fast neutron absorbed dose. There are many ways to measure neutron absorbed dose. However, in recent years, several international comparison held by the situation, the most widely used
