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.

A simple fuel performance code, SESAME, has been developed to analyze the steady-state irradiation behavior of metallic fuels. Important characteristics of metallic fuels such as fission product gas release, swelling, material redistribution, bonding sodium infiltration, and axial elongation are studied. Simple models have been developed for the SESAME code, which have been found to be successful in predicting irradiation data and useful in investigating the basic mechanisms that contribute to these particular irradiation behaviors of metallic fuels.
