Bertin Technologies, a CNIM Group subsidiary, has announced the launch of its new SaphyGATE G range of radiation portal monitors. The first devices in this range of portal monitors automatically detect the potential radioactivity of vehicles, such as trucks and trains, and their loads. Dedicated to the control of radiation hazards on industrial and civil sites, these devices offer excellent measuring performances and meet the requirements of IEC 62022 international standard, one of the most demanding in the field.
It is not uncommon to observe radioactive sources in freight vehicles. Some accidents, related to radioactive material flows management, have been recently recorded worldwide, causing the spread of nuclear material, sometimes in manufactured products. These accidents have serious economic, environmental and human consequences, including several cases of death.
Designed by Bertin teams in France, Italy and Germany, the new SaphyGATE G50 and G100 portal monitors incorporate high-performance detectors. Vehicles to be checked pass between the detectors, installed in pillars. The readings obtained by the detectors are analyzed in real time by the processing system on the control station. To obtain the most accurate possible readings, Bertin Technologies developed an innovative algorithm, designed to compensate the radioactive background attenuation induced by the vehicle driving through.
