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.

Inertial Fusion (IFE) optics presents a unique challenge. Ghoniem provides a mirror design for such an application. The surface has been chosen to be metallic, because dielectric materials exhibit great sensitivity to the effects of ionizing radiation. The leading high reflectivity candidate materials are aluminum, magnesium, silver, gold and copper. To select between these metals the following criteria were used:1) high reflectivity in the wavelength of interest2) effects of radiation on absorptivity3) surface temperature rise during the laser pulse4) thermal fatigue resistance5) radiation effects on surface deformation
