Radioisotope Identification and MCA's (Gamma and Gamma/Neutron)


The devices listed in this section are able to identify radioactive isotopes by analyzing the characteristic gamma emission spectra. Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, in the nuclear laboratory and nuclear process, and in geochemical, astrophysical and other radiation measurement contexts.


Hand-held Radioisotope Identification Devices (RIIDs) take this another step further and are designed to identify the isotopic composition of radioactive sources is a small, handheld device that is generally easy to use and deploy. The devices are often multipurpose/multitask instruments able to detect different forms of radiation and perform a variety of functions; used to search, detect and identify radioactive materials.




The FLIR identiFINDER2/R400 is a logical extension of the original identiFINDER series of handheld radioisotope identification detector (RIID) instruments. The thousands of identiFINDERs currently deployed worldwide have provided ICx with a tremendous resource for suggestions and comments on how to improve the already exceptional identiFINDER. The identiFINDER2 is the result of these comments and suggestions.
