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.

Recent tandem mirror operations are summarized. These include potential formation without sloshing ion beam injection, MHD stability, axial potential confinement, and radial transport. As a result of potential plugging, ion temperatures of 10 keV are achieved. Beta values up to 14 % are also observed, and thermonuclear fusion neutrons are detected. Suppression of drift waves due to ExB shear flows is identified as a key factor for the good radial confinement Work to be done in present-day devices and future prospects are discussed.
