The three modes of operation are intuitive and easy to interpret. The system is complete and eliminates the need for an external computer for operation or analysis. Upon power-up the instrument automatically indicates identified isotopes, their category (medical, industrial, Special Nuclear Material, or custom categories) and calculates isotope specific dose rate. Calibration of the SAM 935 is initiated by simply pressing one of the unit's four soft-key controls with a Cs137 source present. The SAM 935 utilizes advanced gamma-spectroscopy technology and a proprietary Quadratic Compression Algorithm (QCC) within the system's firmware to accurately and reliably identify isotopes within 1 second. This technique insures minimal false alarms and confidence levels above 97% even when users are detecting and identifying weak sources below background levels of intensity. The SAM 935 has a unique feature that tools out continuum including Compton and Bremsstrahlung. This algorithm enables users to identify low energy peaks in the presence of intense high energy isotopes and x-ray backscatter. The SAM 935 time slice technology coupled with its continuous background subtraction enables the instrument to monitor moving vehicles, cargo, RDD (dirty bombs), environmental samples, as well as buildings and portals. Equipped with the SAM 935, the users are able to ID and measure the intensity of isotopes, determine risk scenarios and enact appropriate standard operating procedures immediately. Shows detected isotope intensity as sigma (standard deviations) above background. "Easy Mode" operation is automatic. Continuously displays identified isotopes, category, isotope specific dose rate and neutron count. Live spectrum being acquired is displayed and updated each second. MCA performs analysis on present or stored alarms and prepares a multipage report for printing or email. Monitor Mode Real Time Surveillance Detail-MCA
