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 new semi-empirical formula with five parameters has been derived to systematize the (n,t) cross section data of 14.5MeV neutrons. It is based on the evaporation model and uses the droplet model of Myers and Swiatecki to express the Q(n,t). The behavior of the different terms of the droplet model involved in Q(n,t) was checked individually before choosing the pertinent terms and setting up the formula. This relation leads to the lowest value of 2 compared with the existing formulae, when used to correlate the experimental (n,t) data for 25 nuclei.
