SAM 935


SAM 935 is a portable radiation detection and identification device. It uses gamma spectroscopy with room temperature NaI detectors, and QCC, Quadratic Compression Conversion, algorithms to identify multiple isotopes in realtime and below background. The SAM, surveillance and monitoring, is able to capture even transient phenomenon such as in portal situations because it captures spectra in short time segments and produces a response from spectra with each time segment. Conversely, if the SAM is in a moving vehicle, it can quickly scan an area as the vehicle moves. The first line responder can email the SAM 935 data report for further analysis.
An upgrade to the SAM 935, the SAM 940, uses a LaBr3 detector that has better resolution than a NaI detector. Additionally, the SAM 940 offers one-hand operation and a better display. An advantage of LaBr is clearly seeing the gamma and x- ray peaks of plutonium. The one highly penetrating NaI peak of Pu239 is now clearly separated into three easily recognized peaks with LaBr.
