The identiFINDER® R440 is a lightweight, source-less radionuclide identification device (RID) that delivers sensitive detection and fast results for routine survey or secondary screening response missions. The R440 is available with NaIL, NaI, LaBr and CLLBC detector options to respond to radiological threats from farther away, behind heavier shielding, and with better resolution than similarly-sized RIDs. Its light weight makes single-handed operation easy during extended operations, while the IP67-rated enclosure is built to survive. The bold, easy-to-read interface with 360° EasyFinder™ mode expedites decision-making to keep personnel and the community safe.
