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.

Chromatographic separation of hydrogen isotopes, protium and deuterium, was carried out experimentally using a four-column Pd bed system. The system was operated under the conditions of atmospheric hydrogen pressure and swing of column temperature of 303 K to 473 K. Maximum deuterium enrichment ratio defined as the ratio of the deuterium concentration in product to that in feed was around 100 independent of the deuterium concentration. The deuterium recovery ratio was more than 0.5. Effluent curves were analyzed by the numerical simulation by the plate model. Close agreement was obtained between experiment and analysis. High enrichment of deuterium was also successfully achieved by frontal chromatography using a comparatively large column.
