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.

The operating characteristics of traveling wave direct energy converter, which is expected to be used in an advanced fusion, are discussed in the case of broad energy band flux based on the deceleration theory. Comparison of distributions in phase space between different relative phase differences shows a good agreement with the theory. The examination by narrow energy band flux roughly explained that the observed low energy component corresponded to the incident ions around the best matching energy of the decelerator.
