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.

Magnet alignment in the Mirror Fusion Test Facility-B (MFTF-B) tandem mirror has been measured by electron beams propagated along the axis. A least-squares fit to the data has been obtained by use of singular-value decomposition techniques. This fit determines the positions of the magnets that sensitively effect displacements of the field lines from alignment and, thus, the net geodesic curvature that drives radial transport. The magnets are determined to be aligned accurately enough that the MFTF-B trim coils can correct the field errors and reduce the neoclassical radial transport to an acceptable value.
