The Model 52-8 is a weather-resistant, portable scintillation portal monitor designed for beta/gamma radiation detection in both vehicles and personnel. It features two plastic scintillation detectors, housed in weatherproof, dust-tight, and impact-resistant cases with wheels and tow handles. The microprocessor-based electronics are contained in a matching case and include an On/Off toggle switch and an optional red/green strobe light. The system is highly sensitive, detecting very low levels of radiation from individuals or vehicles passing through the portal. It offers easy setup, adjustable audio signals, and a user-friendly LCD display that shows detector counts, background levels, and system parameters. The Model 52-8 can be powered via a vehicle cigarette lighter plug or batteries, making it versatile for various situations. It meets the Federal Emergency Management Agency (FEMA) standard for Emergency Management Response Portal Monitoring (FEMA REP-21).
