1Overview
The Model SAM 950 Ruggedized Isotope Identifier is the only RIID available with an internal, hardened 3"x3" NaI detector option. The higher sensitivity associated with the large volume NaI detector ensures rapid screening of low activity threats, detection of masked or shielded isotopes, and quick spectroscopic analysis. The SAM 950 also offers users a smaller light-weight optional NaI detector as well as an optional solid-state neutron detector.
Users will love the interface, following touch movements common to smart phones. You can expand on peaks in a spectrum to take a closer look at the energy peaks, or swipe sideways to additional alarm and event details. Once a report is generated, quickly append the report with photos, voice memos and video.

3Detector & Performance
The SAM 950 accepts a range of detector sizes and crystal types. NaI(Tl) is standard. LaBr3 and CeBr3 are optional where higher energy resolution matters. A gain-compensated Geiger-Muller (GM) tube extends dose-rate coverage, and an optional solid-state or 3He neutron detector adds neutron sensitivity.

|---|---|---|
| NaI(Tl) Sodium Iodide | 1.5"x1.5", 2.0"x2.0", 3.0"x3.0" | < 8% |
| LaBr3 Lanthanum Bromide | 1.5"x1.5" | < 3% |
| CeBr3 Cerium Bromide | 1.5"x1.5" | < 4% |
| GM Tube | 2.0"x2.0" | Gain Compensated Geiger-Muller Detector |
| Solid-state or 3He neutron (optional) | – | Neutron detection |
Solid State neutron area: 4 cm² active area, 20% thermal N eff., γ rej. 1:107.

9Product Enhancements
The SAM 950 has been enhanced with some useful application specific tools:
- See the new LED Flashlight for nighttime operations or analysis indoors in poorly lit areas (warehouse, duct systems, storage containers, etc.).
- The shoulder mount clips have been repositioned to balance the weight equally for the end user when operating for long details.
- An added GM-Tube offers alarm indication and high count rate measurements in the event that the NaI detector is saturated. Follow the on-screen directional arrows (Move Back, etc.) to obtain accurate Isotope Identification and Spectroscopy.
- A convenient Tri-Pod mount is included on the underside of the instrument, enabling fixed geometry spectroscopy or monitoring packages and personnel.
