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 atomic displacement and hydrogen and helium gas production rates in a 0.01-m-thick Type 316 stainless-steel first wall have been calculated as a function of the composition of a 0.5-m-thick fusion reactor blanket. The atomic displacement rates range from a low value of 8.4 dpa/yr for an empty blanket to a high value of 22.6 dpa/yr for a lead-filled blanket. Hydrogen gas production rates vary from 423 to 536 appm/yr, and the helium gas production rates vary from 134 to 159 appm/yr for the empty and carbon-filled blankets, respectively.
