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 thermal conductivity of loose, pyrolytic carbon-coated fuel particles in helium was studied at temperatures from 1800 to 2700°F using a convenient comparative technique. The conductivities of coated particles with both 150- and 795-µm overall diameters were shown to rise and then remain constant as the helium pressure was increased to 4 atm. Measurements using particles with various coating thicknesses and structures indicated that bed conductivity was relatively insensitive to the properties of the coating.
