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.

No reaction was observed between B-type 244Cm2O3 and tungsten, molybdenum, or rhenium matrices in cermet compacts fabricated by cold pressing and sintering at temperatures up to 1850°C. Reaction was observed, however, between the oxide and tantalum matrices sintered as low as 1400°C. Cold pressing and sintering at the highest temperatures produced generally well-consolidated Cm2O3 refractory metal compacts of 85% or greater theoretical density. In compacts produced from well-mixed powders, the oxide was distributed uniformly in the metal matrix with little vaporization loss of Cm2Os.
