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.

Heavy impurity ions can be removed from the toroidal magnetic trap in the helical magnetic field of a conventional torsatron or heliotron with the use of an alternating current (ac) electric field. The passing particles can be transformed into helically trapped ones and escape from the magnetic confinement volume by the drift of the particles in the inhomogeneous magnetic field. The frequency of the ac electric field is taken close to the bounce frequency in the helical magnetic field. The analysis is carried out on the basis of guiding center equations.
