| 摘 要： | 为实现矿石品位仪的结构优化，利用蒙特卡罗（MCNP）软件，构建几何模型，模拟伽马射线在矿石品位仪系统内的输运过程。比较两种伽马放射源^60Co和^226Ra的测量效果差异，并分析了放射源与伽马探测器安装位置对测量效果的影响。结果表明，提高矿石品位仪测量效果的有效手段主要有：采用^226Ra放射源取代^60Co放射源；减小探测器与放射源距离；放射源与物料的距离调整为约30cm。

| Abstract: | The MCNP software was used to simulate gamma reaction in a realistic geometric model of ore grade analyzer to optimize the analyzer＇s structure design. The measurement performance on the two kinds of gamma radiation resource, ^60Co and ^226Ra Ra was compared, and the effect to measurement caused by installing location between radioactive resource and gamma detector was analyzed. As a result, there were three methods to improve the measurement performance for the ore grade analyzer： substituting ^226Ra for ^60Co radioactive, reducing the distance between detector and radioactive source, adjusting the distance between radiative source and material to 30 cm around. |
