The invention relates to the technical field of radioactive measurement, and provides a proportional counter processing method which comprises the following steps: standard tritium gas is introduced into a proportional counter to obtain a target pulse signal of the standard tritium gas; obtaining a first charge integral, a second charge integral and a target shape discrimination factor according to the target pulse signal; and according to the first charge integral and a target shape discrimination factor, a discrimination line is obtained, and the target shape discrimination factor is located below the discrimination line. According to the processing method of the proportional counter provided by the invention, the background counting rate in the proportional counter can be reduced. 本申请涉及放射性测量技术领域，提供了一种正比计数器的处理方法，处理方法包括：将标准氚气通入正比计数器，以获取标准氚气的目标脉冲信号；根据目标脉冲信号，获取第一电荷积分、第二电荷积分和目标形状甄别因子；根据第一电荷积分和目标形状甄别因子，获取甄别线，其中，目标形状甄别因子位于甄别线的下方。本申请提供的一种正比计数器的处理方法，能够降低正比计数器内本底计数率。
