B-RAD is a portable, hand-held radiation survey meter, capable of measuring the photon dose rate in presence of strong electromagnetic fields. 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, equipped with an extensible telescopic rod, up to 2.5 m, 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 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.
