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.

A thermal model of an OMEGA-scale cryogenic inertial confinement fusion (ICF) target within the layering sphere of the OMEGA Cryogenic Target Positioner was created. A computational fluid dynamics code was used to calculate the temperature profile in the target. The sensitivity of the temperature profiles was modeled for variations in (1) target alignment in the layering sphere, (2) target specifications, and (3) temperature uniformity on the layering sphere’s inner surface. DT-ice non-uniformity in the target was determined by offsetting the center of the ice’s void to a position that minimized the temperature variance of the ice surface. The numerical solutions were compared to analytical solutions when available.
