Highly Sensitive Radionuclide Identification Device
identiFINDER R500

The FLIR identiFINDER R500 is an extremely sensitive and accurate digital handheld gamma radionuclide identification device (RID). Available in two configurations (NaI and LaBr), the R500 quickly detects, locates, accurately measures, and identifies radiation sources. The additional detector volume allows it to identify radioactive material where other instruments cannot. When large areas need to be screened rapidly or there is potential for shielding, the identiFINDER R500 provides superior sensitivity and performance.
