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.

An electron swarm study using molecular gas-rare gas mixtures is briefly reviewed, and the advantage of using these mixtures to evaluate inelastic electron collision cross-section data for molecules through electron swarm study is explained. This advantage also suggests a new procedure for deriving a consistent set of electron collision cross sections for molecules by using electron swarm data measured in pure molecular gas and in the molecular gas-rare gas mixtures alternately. The procedure is detailed by using an example of C2H4. The derived cross-section set for C2H4 covers the energy range where a conventional electron beam experiment is not practical and can be crucial for the quantitative modeling of relevant plasmas.
