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 adsorption behavior of H2O on Li2O surface was studied by ultra violet photo electron spectroscopy (UPS). Valence-band spectra of Li2O single crystal which was exposed to different pressures of H2O vapor were recorded. After exposure of H2O, variation of the spectra was observed. The observed spectra were interpreted on the basis of ab-initio quantum chemical calculation of the electronic structure of Li2O surface which was covered with –OH. The adsorbate-induced features were assigned as the orbital of surface –OH. The surface condition was varied by Ar ion sputtering and heat treatment under D2 gas. The difference of adsorption behavior of H2O in the surface condition was discussed.
