RadHalo Spectroscopic Area Monitors.

RadHalo rapid deployment probes (RDP) and fixed monitors (FM) deliver high precision gamma and neutron radiation measurements and real-time data collection across a wide range of environments and radiation dose rate levels.

For nuclear power and associated emergency response personnel, the RadHalo instruments’ remote monitoring and turn-key data reach back telemetry capabilities eliminate the need to place personnel in risky environments.
