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.

Visco-plastic flow properties of hydrogenic solids are important considerations for the design and operation of continuous hydrogenic pellet extrusion systems. Prior to 2010, the visco-plastic flow behavior of deuterium, tritium, and mixtures of the isotopes was only known at 14 K and no heat transfer studies were available. To address these needs, a Cryogenic Couette Viscometer (CCV) was developed at the University of Wisconsin-Madison. Visco-plastic flow characteristics of solid neon, deuterium, and hydrogen were measured using the CCV from the onset of solidification to sub-cooled solid states over a range of shear rates. This paper discusses the transformation of these measurements, using the Quantum Law of Corresponding States, to predict the visco-plastic flow behavior of solid tritium and deuterium-tritium mixtures. Comparisons of predicted values with experimental measurements are made, where available.
