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 equivalent chromium content of Type 316 stainless steel is shown to be directly related to irradiation-induced swelling in specimens that have slightly different chemical compositions. In some cases, increased concentrations of an α-stabilizing minor constituent—silicon, phosphorus, and molybdenum—resulted in decreased swelling. The relative swelling resistance of alloys having the same carbon and equivalent nickel contents will be higher for those alloys with the higher equivalent chromium content.
