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.

Ideal gas and multiphase flow through porous soil surrounding a nuclear power generating station after a core meltdown accident are analyzed with dimensionless variables. Results are applicable to many soil conditions. The extent of radioactive fluid penetration into the soil, predicted using methods originally developed by Morrison, indicates that years are required for activity to reach the ground surface if silty clays are present but only ∼ 10 h if a path of sand is included. Source pressure decay caused by mass flow into the soil is small if the normal conditions of a large containment shell volume and low soil permeability exist.
