RadHalo RDP and FM Area Monitor

Spectroscopic area monitor with a NaI detector for continuous dose rate monitoring and nuclide identification, as a portable unit (RDP) or a fixed installation (FM).

The RDP version can withstand drops of up to 1 m onto concrete and has a handle and a removable shoulder strap. All RadHalo model kits contain the RIIDView PC spectra viewer, an AC power supply and an Android/Apple mobile device application, and data can be transferred to Thermo Scientific ViewPoint or your own command and control software.

  • Measures dose rate and identifies nuclides automatically, with a 3x3" NaI detector and a dual range Geiger-Mueller tube
  • Portable RDP for rapid deployment, fixed FM for permanent area monitoring
  • 60 hr battery that can be charged via AC mains or solar panel
  • Monitors the communication channels and automatically switches if the primary transmission method is unavailable
  • 1024 bit encrypted data transmissions and tamper sensors
