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 neutron-capture resonance integral of 233Pa has been measured by irradiating cadmium-covered thorium wires, and, after suitable chemical separations, determining the quantity of 234U produced. Results are reported for two methods of measuring the irradiating flux. Monitor wires of cobalt in aluminum alloy give integrated fluxes based upon a value of 72.0 b for the resonance integral of 59Co. Alternatively, measurements of the 233U produced by the irradiations give integrated fluxes based upon an effective resonance integral of 36.5 b measured for the 232Th wires. The experiments provide 233Pa resonance integral results of 846 ± 43 b employing cobalt-monitored fluxes, and 837 ± 43 b employing thorium-monitored fluxes. These results, which have an average value of 842 ± 35 b, include the l/ν component of the cross section, and are appropriate for a 1/E spectrum and a perfect filter with a low energy cutoff of 0.50 eV.
