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.

Achieving high-performance long-duration plasma discharges in tokamaks is one of the most important challenges to be addressed in the perspective of the development of a power plant. For this purpose, real-time handling of off-normal events has to be performed through a dedicated plasma discharge management system. In this paper, we describe the main requirements and features of such a system. A generic architecture, based on the principle of subsidiarity, is proposed. A full set of actions is covered, starting from the local subsystems up to the tokamak as a whole, with different levels of mitigation strategies. A simulation of a relevant test case, based on the Tore Supra tokamak, showing the basic principles of the study, is also presented.
