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.

Quantitative correlation factors and functions are derived that relate the inside peak heat fluxes for cases involving either a single-side or a uniform external heat flux, which is applied to a circular coolant channel. The results are also presented in terms of a map that gives insight on how to improve high-heat-flux accommodation. The results show that similarities and differences depend on the channel geometry, material, and internal convection.
