The TSA Systems, Ltd. VM-250 SNM (special nuclear material) portal monitor originated as a drive-through radiation measurement system for detecting the presence of SNM in motor vehicles. The VM-250 now is also used as a walk-through SNM monitor for pedestrians. This manual describes the VM-250 monitor, how to calibrate its signal conditioning electronics, and how to set its variable operating parameters. The manual also describes a test procedure for verifying the monitors performance. 5 figs., 2 tabs.
