As part of the radiological monitoring of workers exposed to ionizing radiation, IRSN provides dosimetry services by continuing its R&D efforts to make available state-of-the-art dosimeters. This is the case for the "new generation" RPL-neutron dosimeter, which was put into service on January 1, 2022. 

The result of two years of R&D and feedback from users of the previous dosimeter, this new design offers robustness and lightness for an equipment that combines the technology radiophotoluminescence (RPL) and neutron detection technology, enabling the monitoring of workers exposed to X-rays, gamma and beta radiation as well as neutron radiation in the context of their professional activity, mainly in industry or research.

Its new shell was designed and produced 100% by French companies partnering with the Institute. In a CSR approach, it is made of recyclable plastic. Finally, it is lighter and has a new, more ergonomic and robust hanging system.
In parallel with these innovations, IRSN is continuing its R&D work to develop a dosimeter with even better metrological characteristics for the neutron component.
