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.

Titanium and titanium alloys are not generally resistant to mercury in the temperature range between 371 to 538 C. The extent of corrosion is dependent upon alloy composition and heat treatment. Nitrided surfaces of titanium and its alloys exhibit high resistance to mercury at 538 C for periods up to 14 days. At this temperature, mercury vapor attacks certain nitrided alloys while others are immune. For instance, the corrosion of a nitrided Ti/8wt% alloy was found to be insignificant; however, severe corrosion occurs at the nitrided layer of Ti/7wt% Al/12wt% Zr.a A study of the effect of metallic additives to mercury on the corrosion resistance of titanium at 538 C has also been made. It has been shown that a saturated mercury solution of zirconium or nickel exerts a strong influence in reducing corrosion. The films formed may act as a diffusion barrier between solid and liquid.
