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.

Measurements have been made to determine the effect of mutual shielding on the resonance absorption of neutrons by tightly packed thorium oxide lattice pins. From these measurements, correction factors have been obtained for reducing the results of single-pin resonance integral measurements to the effective lattice values. A comparison of the experimental results with the predictions of the theory of Dancoff and Ginsburg is included.
