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.

Possibility of metal coatings on F82H as the tritium permeation reduction coating was examined by means of deuterium permeation experiment. Metal coatings such as copper, aluminum and gold plating of 10 m thickness on outer surface of the F82H tube (250mm length, 10mm diameter and 1mm thickness) were prepared as the permeation reduction coating. Permeation Reduction Factor (PRF) of the metal coatings was evaluated by comparing the steady state permeation flux between metal plated specimens and F82H specimen. As the results, the PRF of the metal coatings at 590K were 5, 100 and >1000 for copper, aluminum and gold plating, respectively. Those results indicate the possibility that aluminum and gold plating could be applied in the tritium system as the tritium permeation reduction method.
