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.

Several recent papers have investigated the effect of ignoring bulk recombination in derivations of the sink strengths required for the rate theory of void swelling, irradiation creep, and growth. Although most of this work has concluded that bulk recombination can safely be neglected in such procedures, some uncertainty remains. Numerical calculations to eliminate this uncertainty have been made that compare explicit spatial grid and continuum representations of a thin foil, and are performed for irradiation growth in zirconium. It is found that the growth strain predicted using the continuum foil sink strength, derived without bulk recombination, is always within ∼20% of the spatial result and is usually in much closer agreement.
