Radionuclide Identification

identiFINDER® R425: Fast, trusted radionuclide ID in the field.

Purpose-built RIID for defence, border, and emergency teams. Detects, locates, and identifies gamma (and optional neutron) sources with NaI(Tl) or LaBr₃(Ce) detectors. Ruggedised for harsh environments (IP67, MIL-STD-810G Salt/Fog) with 360° awareness and high-dose handling up to 1000 R/h. Modular hardware, companion RadMobile/RadRemote app, and N42.42 data keep your end-to-end workflow—from alarm to reachback—tight and auditable.
