Guardian™ VM1000S Series of spectroscopic radiation portal monitors (SRPM) accurately detects, identifies, and classifies radionuclides concealed in passenger vehicles, freight trucks, and trains. With three gamma detector configurations to choose from, this drive-through SRPM arrives on site customized for the application and location. Additional sensitivity refinements can be made by security personnel, whether local or remote, using the system’s industry-leading software. This supports exceptional NORM rejection, resulting in a near zero false alarm rate which maximizes throughput and minimizes the need for time-consuming manual inspections.
