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.

Several sets of 239Pu neutron cross-section data have been analyzed with the R-matrix Bayesian program SAMMY up to 30 eV. The cross sections computed with the multilevel parameters are consistent with recent fission and transmission measurements, as well as with older capture and alpha measurements. The Reich-Moore-type-R-matrix resonance parameters were converted into equivalent Adler-Adler-type parameters using the computer program POLLA.
