摘　　要：金箔在中子场中活化后,采用4πβ-γ符合测量装置测量活化片活度,由此得到了孔道中热中子注量率,将该测量结果与MCNP软件计算结果进行了比较,两者在6%偏差范围内保持一致。The activity of Au foil was measured by 4πβ-γ coincident device when the foil was activated in neutron field.The neutron flux could calculated by the activity.The flux was calculated by MCNP software also and the deviation was less than 6%.

关 键 词：金活化法 中子注量率 绝对测量
