摘　　要：表面污染仪广泛用于环境、核医学、商检、卫生、核电、农业等领域的表面污染测量与监测,其准确测量对于工作环境以及工作人员的安全有非常重要的意义。本文采用FJ-2207型α、β表面污染仪,对测量距离、材料吸收、探测器各部位灵敏度的不一致性、不同射线干扰、能量响应等影响表面污染仪测量结果准确度的几个因素进行了系统研究,确定了相关影响量,对正确使用各种表面污染仪,保证测量结果的准确可靠提供了指导。The surface pollution monitor was widely used in environmental, nuclear medicine, commodity inspection, health, nuclear power, agriculture and so on. And the accurately measurement will be of great importance in the safety of the environment and the workers. In this paper, we use type FJ-2207 α, β surface pollution monitor to research several factors which affect the measurement accuracy of surface pollution monitor, such as distance, absorption, the inconsistency sensitivity of different parts of detector, ray interference, energy response, and so on. And we confirmed the relative influence quantity, this will give some guidance for proper use of a variety of surface contamination meters, and ensure accurate and reliable measurement results.
