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.

Abnormal flows such as an entrainment or an overflow have been restricted severely in the design and operation of the solvent extraction process. The effect of the abnormal flows on the process has been studied for a PUREX flow sheet to find a way to manage their unfavorable effects on the process. As one of these activities, the algebraic equation expressing the concentration of the outflow by the operational conditions for a countercurrent solvent extraction system with the existence of abnormal flows was derived. This equation was the expanded form of the conventional Kremser's equation, which has been applied to the flow sheet under normal conditions. The preliminary study using the equation is also shown.
