SaphyRAD probes

Expert interview:

SaphyRAD, universal contamination meter with improved ergonomics

Julien Villert, Bertin’s Health Physics Product Manager, explains how the innovative probes of the SaphyRAD radiation contamination meter have been enhanced. Designed for EDF, this instrument has been enriched to suit the needs not only of the nuclear market, but also nuclear medicine, research and industry. Thanks to its alarm and distance control indicators, and its configurable radionuclide library, it is easy to use in all fields requiring radiation contamination detection, even by non specialists.
