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.

A review of some characteristic features of the boronization process, properties of boron-carbon films, and the influence of these features on tokamak discharges is presented. Boronization, as defined here, is a plasma chemical vapor deposition of a thin a-B/C:H film on the first wall of fusion reactors. As a result of boronization, oxygen, carbon, and heavy impurities (e.g., iron, nickel, and chromium) are suppressed, and hydrogen recycling is reduced, which substantially improves the characteristics of tokamak discharges. A two-stage complex protection of both the first wall by boronization and of limiters, divertor plates, and radio-frequency antennas by the application of thick B4C coatings provides further improvement of tokamak plasma parameters.
