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 volumetrically-loaded ultra-high-density deuterium cluster material is described here for use as a deuteron beam source in laser matter interactions. Due to high volumetric loading, the material has potential to provide enough deuteron beam flux for the inertial confinement fusion (ICF) fuel ignition, avoiding depletion problem encountered by current proton-driven fast ignition (FI). In addition, accelerated deuterons can fuse with the ICF fuel (both D and T) to provide extra “bonus” energy gain, which further relaxes the laser-driver energy needed. Preliminary TRIDENT sub-Petawatt Laser experiments have provided some encouraging results showing that our cluster foils with a relative low packing fraction, can achieve a high yield of the accelerated deuterons even in the presence of an unwanted surface contaminant.
