B-RAD Gamma Radiation Survey Meter (LaBr3)

HAND-HELD RADIATION SURVEY METER FOR GAMMA RADIATION
B-RAD is a portable, hand-held gamma monitor, capable of providing the photon spectra in presence of strong electromagnetic fields.

Description

It has been tested to work properly in magnetic fields up to 3 T. For comparison, conventional devices fail to operate at intensities as low as 0.1 T.

Light and compact, B-RAD is ideal for radiation surveys and for local measurements of contamination or residual radioactivity in hot spots. It also includes a Hall probe connected to an indicator for a rough measurement of the magnetic field in which it is operating

B-RAD employs a high sensitivity LaBr3(Ce3+) crystal directly coupled to a Silicon photomultiplier (SiPM) matrix.

The excellent scintillation properties and the high photon resolution of the scintillator (3.3% FWHM at 662 keV) make the device capable of operating over a wide energy range with a very fast response, i.e. reducing at minimum dead time-related issues.

This technology has been originally developed at CERN, and has become the standard for radiation surveys in the Large Hadron Collider (LHC) experiments. It is commercialized under an official license granted by CERN, with the “CERN Technology” label.
