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 statistical model is used to interpret the available 232U(n,f) cross-section data in the neutron energy range from 0.003 to 7.4 MeV Below an incident neutron energy of ≈ 1 MeV, the nonthreshold energy dependence of the 232U(n,f) cross section is interpreted in a double-humped fission barrier model, the inner barrier of fissioning nucleus being ≈1 MeV lower than the outer one, as anticipated with the shell correction method calculation.
