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.

A NaI(Tl)-based in-line enrichment monitor has been developed for the gas-phase UF6 feed stream of an enrichment plant to provide real-time material-accountancy and/or containment-surveillance data. The method has produced assay results that are independent of operating UF6 pressure, with an assay accuracy of better than 1% (1σ) relative over the range of UF6 enrichments of 0.72 to 5.4 at.%. For 1.0%-enriched UF6 at 700 Torr, a 0.74% relative precision was obtained for a 1000-s counting time. As a result of these measurements, an in-line gas-phase enrichment monitor has been installed in the Paducah-product feed line of the Oak Ridge Gaseous Diffusion Plant for field test and evaluation.
