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.

The CASMO code is an assembly spectrum code that uses multigroup integral transport theory with four thermal energy groups for the two-dimensional calculation. The latest version, CASMO-3, contains several new features, specifically a new data library, multibundle capability, gamma detector calculation, flux discontinuity factor edit, and an option for generating transport theory corrected baffle/reflector data. Extensive benchmarking, including comparisons against cold- and high-temperature critical experiments, Monte Carlo calculations, measured isotopics, and power reactor core follow, has verified that accurate results are obtained. The new multibundle capability has been used for studies of interassembly spectrum coupling and for validation of core physics methods.
