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 corrosion behavior of Type 316L stainless steel in stagnating liquid Li under an elevated-temperature environment was investigated using a scanning electron microscope and an energy dispersive X-ray detector and self-designed laser-induced breakdown spectroscopy. A nonuniform and cell-like branched structure separated by distinct boundaries was observed, and a porous and rugged corroded layer was formed on the surface of the substrate after 500 h exposing 350°C liquid Li. This showed that the intensity of the Cr element on the superficial corroded sample decreased significantly when the depth reached ~2.8 μm and then was gradually restored in the range of ~5.6 μm. Meanwhile, the intensity of the Li element revealed consistent reduction to zero at ~4.0 μm. This study disclosed element transfer and penetration along a depth in the corrosion process between the liquid lithium and steel matrix.
