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.

The branching processes involving all first-generation progeny reaction products of deuterium-based fusion systems are investigated. It is shown that a generalized formulation of various deuterium-deuterium burn modes can be specified and explicit expressions for the extent of branching established. Specific branching ratios and selected associated rate expressions are evaluated for the case of catalyzed fusion modes sustained for steady-state burn by appropriate ion seeding.
