芒特·艾萨矿业公司炼铅厂已经在全厂范围内引入了用于监测空气飘浮烟尘中含铅量的联机监测系统。该系统是以5台放射性同位素X射线荧光监测仪为基础用以测量空气中的飘浮尘粒,通过共用的数据处理系统与炼铅厂的过程控制计算机联接成一网络。每台监测仪每小时对周围大气中的铅含量进行测量並直接以微克/米~3数值显示出来,所有来自监测仪的监 The Mount Elsa Mining Company smelter has introduced, throughout the plant, an on-line monitoring system for monitoring the lead content of airborne fumes. Based on five radioisotope XRF monitors, the system measures floating dust in the air and is networked through a common data processing system with a process control computer in the smelter. Each monitor measures the amount of lead in the surrounding atmosphere every hour and displays it directly at a value of micrograms / meter to 3 meters. All monitors from the monitor
