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 use of Tnτ as a measure of plasma quality appears to be a significant improvement over the Lawson criteria, nτ, as fusion plasmas approach the ignition goal of fusion research. Comments are made to urge a revival of interest in plasma density exponentiation and the “need to know” of the burn characteristics of fusion plasmas.
