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.

CH capsules, produced with glow discharge plasma coating, pick up oxygen continuously and irreversibly during storage. The added X-ray opacity from this oxygen affects the shock velocity during target implosion, requiring compensation in the shock timing. We developed a radiography technique that nondestructively characterizes the oxygen profile and have used it to track the evolution of the oxygen profiles in various types of storage conditions. Modified storage protocols have reduced the amount of pickup, and our database enables estimation of the oxygen profile at shot time such that the impact on target implosion performance can be minimized.
