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.

Multidimensional transport simulations using the BALDUR code have been used to examine the correlation between the effective global helium particle confinement time and the edge recycling coefficient with profile effects included. This provides a way to benchmark the widely used zero-dimensional model so that a first-order correction for these effects is possible. It is shown that the predictions of the effect of recycling on helium confinement using the benchmarked zero-dimensional correlation agrees fairly well with the BALDUR results.
