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 study was carried out to ascertain the diffusion and adsorption parameter values for tritiated water in contact with palladium-silver cathodic membranes with and without palladium black deposits. It is shown that the amount of diffused and trapped tritium, the retrodiffusion, diffusion coefficient, tritium concentrations in the alloy sublayer, and diffusion layer thickness depend on the applied cathodic potential, temperature, palladium-silver membrane thickness, palladium black deposits on the cathodic surface, and time. With a palladium black deposit on the palladium-silver, the tritium adsorption and diffusion increase. Parameter values including the activation energy are determined from electrochemical impedance spectroscopy, voltammetry, permeation experiments, and chronocoulometry.
