Field pollution diffusion detection system and detection method

The invention discloses a site pollution diffusion detection system and method, and the system comprises a pollution detector, an anemorumbometer, a host, and a wireless router, and the host helps rescue personnel to predict a region where nuclear radiation pollution is about to be polluted in a set time range through the data of a site polluted region, the pollution degree, the wind direction, and the wind speed. And rescue personnel take the wounded person to evacuate and transfer to a safe area for rescue, so that the rescue personnel and the wounded person are guaranteed, and the wounded person is prevented from being secondarily hurt. 一种场所污染扩散检测系统及检测方法，包括污染检测仪、风速风向仪、主机、无线路由，主机通过场所受污染区域及污染程度、风向及风速的数据，帮助救治人员预测在设置的时间范围内核辐射污染即将污染的区域，救治人员带伤员撤离并转移至安全区域进行救治，保障救治人员和伤员，避免伤员受到二次伤害。
