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 fracture behavior of several tungsten based alloys was characterized by standard Charpy tests which have been performed up to 1100°C in vacuum. Due to their fabrication history (powder mixing, pressing, sintering, rolling) all materials had specific micro-structures which led to typical delamination fractures. The influence of notch machining method was also investigated. All results are discussed and assessed with respect to the optimization of future divertor component fabrication.
