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 new interpretation of the in situ TRIO experiment on tritium release from γ-LiAlO2 ceramic particles is presented. It is suggested that, due to a very small ceramic particle radius (R = 0.1 µm), the release-controlling phenomenon is desorption of tritium-containing molecules from the particle surface rather than tritium diffusivity in the particle. This hypothesis eliminates the large discrepancy with previous tritium diffusivity experiments with large particles, where the time-controlling phenomenon is clearly diffusivity.
