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 results of a series of irradiations of refractory fuels at cladding surface temperatures from 1000 to 1900°C were examined to determine which factors have the greatest influence on swelling rates at high temperatures. The effect of temperature on swelling rates is so large that it was found desirable to plot the data as Arrhenius functions of temperature in order to assess the relatively smaller effects of cladding restraint, stoichiometry, burnup, distributed voidage, cracks, and other factors.
