Radioactive Isotope Identification Device （RIID）

The SAM 940

New radioactive isotope identification instruments from Berkeley Nucleonics Corporation （BNC） offer specialized options

for use in the health physics, law enforcement ａnd homeland security industries. 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.

Detector Options:

The SAM systems offer several detector choices:

Sodium Iodide: For isotope identification, good efficiency ａnd optimum price/performance, the Sodium Iodide option

（NaI） gives users fast ａnd accurate identification at an excellent value. The NaI option utilizes advanced algorithms to

discriminate peaks ａnd identify sources in real time.

Lanthanum Bromide: For the professionsal spectroscopist, an optional LaBr detector is available for the SAM system.

This new material offers the end users a typical resolution of 2.8% at 662 KeV ａnd ensures the spectroscopic reports have

unparalleled analytical capability.

Lithium: For Sensitive Nuclear Material detection or safeguarding of WGPu, the Lithium （6Lil） option for the SAM

system allows users to alarm on neutrons ａnd perform a variety of coincidence checks, comparing peak analysis with the

presence of neutron radiation.

First Isotope Identifier RIID Designed After ANSI 42.34

For years, the Surveillance ａnd Measurement System （SAM） family of instruments has been synonymous with high overall

performance in a portable isotope identifier. The earliest SAM model was the first real-time radiation area monitor capable

of isotope identification in one second. A later model was the first device to give field operators the ability to identify

sources on the move without having to stop ａnd hold position while the instrument collected data. BNC continues its legacy

of technical progression with the release of the Model 940 designed in response to ANSI 42.34 （American National

Standard Performance Criteria for Hand-held Instruments for the Detection ａnd Identification of Radionuclides）.

The systems offer a variety of Gamma Detectors ａnd an optional Neutron Detector. A convenient Ethernet connection, CompactFlash

card, USB adapter, or RS-232 ensure easy data storage, archive, or transfer. Spectral reporting is generated in XML compliant

formats according to the ANSI N42.42 standard. An auxiliary port allows the use of application-specific third party hardware

such as a GPS （global positioning system）, Bluetooth data transmission, or wireless 802.11 / ZigBee protocol. The new compact,

portable, ａnd lightweight enclosure is ergonomically designed for single-hand operation which is ideal for downrange use or in

hot zone environments. Whether your work involves emergency response, interdiction, or environmental clean-up, the new SAM

Defender ａnd SAM Resolver will deliver the most advanced tools available in a portable isotope identifier.
