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.

Possibilities for maximizing the tritium breeding ratio (TBR) and for minimizing the major radius of the Next European Torus (NET) fusion device are investigated using the nucleonic optimization code SWAN. It is found that a NET like device can be designed to be tritium self-sufficient even when tritium breeding is restricted to the outboard blanket, while enabling a 25 cm reduction in the major radius of the device, Additional 20 cm major radius reduction is expected from replacing the conventional steel-water inboard shield by an optimized shield based on a tungsten-copper composite material and titanium-hydride.
