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 ability to interpret measured (n, 2n) cross sections by the statistical model of nuclear reactions has been tested. Good agreement was observed for 22 nuclei having mass numbers greater than 30. The statistical model was then applied to nuclei in this mass range to estimate both monoenergetic and fission-spectrum-averaged cross sections. The (n, 2n) reaction in structural materials contributes on the order of +0.1% to the reactor multiplication.
