SaphyRAD Alpha Beta Contamination Monitor

SaphyRAD is a multiprobe handheld device used for the detection of alpha & beta radioactive contaminations.

SaphyRAD multiprobe alpha & beta contamination meter has been developed to meet all needs of contamination control for multiple markets such as the nuclear and NORM industries, medical structures & first responders, thanks to its integrated nuclide library. Its ergonomic interface and design have been especially conceived for use even by non-specialists.

SaphyRAD’s wide range of contamination probes combined with its specific algorithm allow for a very fast and reactive detection. Depending on the probe, the operator can either assess small or large areas to detect alpha, beta/gamma or alpha & beta/gamma radioactive contamination. All data can be stored on an SD card for measurement recordings.

Ruggedized for harsh environment

The SaphyRAD has a robust housing with 6 large buttons designed for use with gloves. This device is adapted to meet the needs of the Nuclear industry, but also of the NORM industry, first responders & medical structures.


SaphyRAD is designed for the detection & measurement of Alpha and/or Beta radiation sources with the use of external connected measuring probes. It has a wide dose rate range from 0.05 μGy/h to 10Gy/h

It is also compatible with external analog probes of other systems.

Ease of use

SaphyRAD is an ergonomic handheld device with a high image quality color screen. Some probes also include an embedded alarm & a distance control indicator.


SaphyRAD works with a specific algorithm which was developed for a very fast and reactive detection of radiation sources.

The SaphyRAD was initially developed for EDF, global leader in low-carbon energy. Its ergonomic design meets the requirements of the Nuclear Industry providing a versatile and ergonomic device. Thanks to its adaptative library of 20 radionuclides, it can also be used for civil and medical applications. The system provides different measurement modes for the measurement and detection of alpha&beta radiations. Its innovative probes are equipped with a proximity sensor and embedded alarm. A clear and easy-to-check bar graph is displayed on the screen in order to facilitate monitoring operations. The SaphyRAD has data storage on a removable SD Card and 45 hours of autonomy thanks to its rechargeable Li-ion battery.

The SaphyRAD is compliant with all european standards especially in terms of compatibility with electromagnetic fields. It is also compliant with the international standard IEC60325.
