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.

Application of resistive magnet tokamaks to fissile fuel production has been studied. The Resistive magnet Tokamak Fusion Breeder (RTFB) uses semi-monolithic Bitter plate toroidal field coils and has a major radius of 3.81 m. with a fusion power output of 618 MWth. An energy-multiplying blanket gives a total blanket power of 4986 MWth, while producing 3742 kg/yr of 233U and 239Pu. The RTFB cost is estimated to be $2.6B.
