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.

Particle discrimination and deceleration are studied with employing experimental devices which simulate direct energy converters used for D–3He reactor. A Cusp-DEC simulator with a slanted cusp field is constructed, and the preparative numerical simulation about it shows the better discrimination is expected for ions with a small pitch angle. Experimental results in a TWDEC simulator are presented. Due to the measurements of energy distribution, the effectiveness of spatially varied wavelength structure is demonstrated. The simple 1-D orbit calculation shows that the efficiency of the same extent as that of the 2-D numerical simulation would be achieved in the experimental device.
