The RAIN scale: A good intention that falls short
Radiation protection specialists agree that clear communication of radiation risks remains a vexing challenge that cannot be solved solely by finding new ways to convey technical information.
Earlier this year, an article in Nuclear News described a new radiation risk communication tool, known as the Radiation Index, or, RAIN (“Let it RAIN: A new approach to radiation communication,” NN, Jan. 2025, p. 36). The authors of the article created the RAIN scale to improve radiation risk communication to the general public who are not well-versed in important aspects of radiation exposures, including radiation dose quantities, units, and values; associated health consequences; and the benefits derived from radiation exposures.

The design of underground and closure structures for the Cigeo repository is mainly based on geomechanical constitutive models tested in the Meuse/Haute-Marne URL. Excavation modes adapted to the different repository components have been evaluated and tested. Specific methods for excavation and lining have been designed for access shafts and ramps, ILW and HLW disposal cells as well as sealing systems located in surface-to-bottom infrastructures and in drifts.
