SAM 945 Handheld Radiation Isotope Identifier with Reachback

An all-in-one RIID that pairs the industry's largest internal detector with modern smartphone technology. The included PeakAbout app handles data, reporting, and remote ALARA control over Bluetooth, so operators stay back from the source while the instrument does the work.

SAM 945 handheld radiation isotope identifier

1Overview

Verification notes. The SAM 945 ships in Lanthanum configurations (models 945-LG and 945-LGN), but the published product page does not list a discrete LaBr3 crystal size. Confirm exact crystal dimensions against the latest released Berkeley Nucleonics datasheet before quoting. ANSI N42.34, IEC, and ITRAP certifications are not stated on the source page; verify certification status with engineering.

The SAM 945 is an all-in-one radiation isotope identifier built for operators who need fast, defensible answers in the field. It pairs a large internal detector with the processing power of modern handheld electronics. The renaissance in smartphone and PDA hardware brought a jump in raw processing speed, and that headroom lets the SAM 945 run statistical calculations and spectral collection at remarkable speed without sacrificing accuracy.

A detachable smartphone interface runs PeakAbout, a free app that manages data and reporting for the instrument. PeakAbout ships with a comprehensive library of 115 isotopes and can expand to 393. The app also enables ALARA practice in the truest sense: operators monitor and control the SAM 945 remotely, keeping distance from the source while the detector stays on target. Berkeley Nucleonics is a world leader in the design and manufacture of radionuclide identification devices, and the SAM 945 reflects that depth.

3Detector & Performance

The SAM 945 carries a large-volume internal detector and supports several scintillator choices, so a single platform covers general identification, special nuclear material work, and high-resolution spectroscopy. A GM tube extends coverage into high dose rates, and an optional 3He tube adds neutron detection.

DetectorApplication
NaI(Tl)General purpose isotope identification (standard)
CeBrSNM enhanced, high resolution spectroscopy
Lanthanum (LaBr3)Available as a configuration (945-LG / 945-LGN); crystal size not published, verify
Large Volume CeriumAvailable as a configuration (945-C2G / 945-C2GN)
3He tubeNeutron detection (optional)
GM tubeHigh dose rates (standard)

Digital signal processing handles between 250,000 and 400,000 CPS on Cs-137. Maximum count rate runs to 100,000 CPS or 150,000 CPS depending on background and the number of energy peaks present.
