SAM 950 Berkeley Nucleonics Corporation 4 of 62
CHAPTER 1. INTRODUCTION
The SAM 950 is designed to meet the requirements of ANSI 42.34 criteria for hand-held instruments for the
detection and identification of radionuclides.
This instrument provides a superb solution for the demanding requirements of emergency responder and
Homeland Security in the USA and other countries. Our solution replaces traditional designs with a unique
solution that seamlessly integrates a powerful PDA or Smartphone with the Nuclear Radiation measuring
detectors.
The SAM 950 unit is designed to accommodate various type and size of radiation detectors, available
detectors are: 2x2 or 3x3 inch NaI(Tl), 1.5x1.5 or 2x2 inch high resolution detectors such as LaBr3 or CeBr3.
The unit also equips a supplementary GM tube which takes over measurement of high dose radiation when it
exceeds 10 mR/h. A solid state neutron detector, ‘Domino’, which has small form factor with superior
gamma rejection than He-3 detector can be added optionally.
One of the most distinctive features compared to the conventional hand-held RIIDs are attaching photo,
video and/or voice/text comments to the event file. In addition, measured events can be sent via WiFi
network to a reach-back center and/or RadResponder site in real time. These feature are enabled by the
powerful smartphone application SW, PeakAbout II.
Data acquisition is securely conducted via wired connection to the Personal Digital Assistant (PDA) unit. The
standard PDA unit is the Samsung J5 or equivalent. The PDA display provides the user with easy to read
information providing assessment of current radiological levels including personal safety and radionuclide
identification. Upon completion of a survey the data may be downloaded from the PDA unit to the PC. The
optional GPS unit provides the data necessary for mapping of the radiation levels.
