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 fast electron loses kinetic energy as it passes through a medium by an amount that depends, among other things, on the distance traveled in the medium. This energy spectrum of electrons has been measured as a function of the distance. In this experiment, the spectrum has been empirically determined using water as the absorption medium. The feasibility of applying the method to other media is also demonstrated.
