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.

Under the assumption of time-dependent net core breeding gain of fusion-fission symbiotic systems, analytical forms for the stockpile fuel trajectories have been derived, both for continuous and discontinuous operation. Also, usable regions for characteristic system parameters such as doubling time, minimum inventory, minimum inventory time, and minimum initial inventory have been defined. It is shown that fuel trajectories defined previously are underestimating the importance of the time dependence of the net core breeding gain.
