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.

Three spinodally strengthened copper alloys were irradiated with fast neutrons to 34 displacements per atom (dpa) at 414°C, 50 dpa at 411°C, and 32 dpa at 529°C in order to assess their suitability for high-temperature service in neutron environments. Density, electrical conductivity, tensile property, and fracture behavior changes were determined with emphasis on the microstructural reasons for the changes observed. These spinodally strengthened alloys were found to exhibit improved properties following irradiation, and they show merit for use in high-temperature neutron environments, although their low initial conductivity may be a limitation. The results are compared to those of high-purity, unalloyed copper.
