为在γ放射性活度很大的测量中使测量系统得到更好的准确度，本文使用干扰源研究 HPGe探测器得到了测量系统死时间与计数损失的关系。在γ能量为0.3～1.3 M eV 时进行实验，使用104～105 Bq量级的放射源，修正能峰的计数率一般保持在几十s－1，证明在误差范围（3％）内，计数损失随死时间变化的关系与射线能量和计数强度无关，任意强度的任意核素均可使用这一修正公式进行计数损失修正。

The relationship between dead‐time and count correction factor was investiga‐ted by using interference source for purpose of high γactivity measurement .The count rates maintain serval 10 s-1 with γ energy of 0.3‐1.3 MeV for 104‐105 Bq radioactive source .It is proved that the relationship between count loss and dead‐time is uncon‐cerned at various energy and various count intensities .The same correction formula can be used for any nuclide measurement .
