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.

Aneutronic energy (fusion with little or negligible neutron flux) requires plasma pressures and stable confinement times larger than can be delivered by current approaches. If plasma pressures appropriate to burn times on the order of milliseconds could be achieved in aneutronic fuels, then high power densities and very compact, relatively clean burning engines for space and other special applications would be at hand. The PLASMAK™ innovation will make this possible; its unique pressure efficient structure, exceptional stability, fluid-mechanically compressible Mantle and direct inductive MHD electric power conversion advantages are described. Peak burn densities of tens of megawatts per cc give it compactness even in the multi-gigawatt electric output size. Engineering advantages indicate a rapid development schedule at very modest cost.
