Radiation Isotope Identification Device


Product Details


Surveillance and Measurement System (SAM) 940 Defender


This radioactive isotope identification device (RIID) offer specialized options for use in the health physics, law enforcement and homeland securities. The SAM Defender (standard resolution) and SAM Resolver (high resolution) are portable radiation identification systems developed to provide simple operation for the first responder who needs to react quickly, as well as detailed analyses for the sophisticated technical user. Several modes of operation give all users the information they need right at their fingertips.
