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.

We investigated the power capabilities and the economic performance of a semicatalyzed-deuterium hybrid reactor with a fissionable blanket fueling a D-3He field-reversed mirror satellite. The hybrid reactor consists of five cells each producing 15-MW fusion power by a total injection of 29 MW of 160-keV deuterium. With a blanket multiplication of four, it supplies a net electric output power of 61 MW, corresponding to an economic figure-of-merit (FOM) of roughly 1800 dollar/kW(electric), which compares favorably with conventional fission reactors. The D-3He satellite is a single-cell reactor of 1 0-MW net electric power, showing a rather high economic FOM of ∼4300 dollar/kW(electric), giving an average economic FOM of ∼2200 dollar/kW(electric) for the combined system.
