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.

Understanding the reason for the divertor flow asymmetry in heliotron/torsatron-type fusion devices is important for the safety of the in-vessel components, such as divertor plates subject to the direct impact of the plasma or the electrical probes and thermocouples for measurements of the particle and energy fluxes to the divertor plates. In previous work, the divertor flow distributions were studied mainly with focusing on the up-down asymmetry in a heliotron-type fusion device, Heliotron E. This paper analyzes the in-out asymmetry of divertor flows and discusses the effects on this asymmetry of the magnetic axis position (the horizontal shift due to variation of the vertical magnetic field or plasma pressure) and power of neutral beams.
