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 Impurity Processing system of the JET Active Gas Handling System has been upgraded to implement a new catalytic reactor for hydrogen-containing gases, such as hydrocarbons and water, decomposition followed by removal of liberated molecular hydrogen using a palladium permeator. Detritiation of hydrogen-containing species is based on their conversion to molecular hydrogen in the reactions with the carbon-nickel composite. The non-active commissioning of the new modules has been completed.
