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 fusion of common wall coating materials is considered in high-temperature plasmas. The concept is attractive since the detrimental effects of these materials as primary impurities are diminished. It is determined that fusion power densities can be increased by including the impurity reactions for a specified impurity content; however, this increase is more than offset by the corresponding decrease in power density due to primary fuel depletion. It is noted that impurity fusion reactions should be included in fuel cycle analyses since ash isotopes may impact the vacuum pumping technology of the reactor.
