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.

Using experimental data from indicator pump tests, various theoretical migration models for radionuclides in groundwater-bearing horizons were considered. The model parameters necessary for these considerations, especially migration velocity and dis-persivity, were obtained by statistical analysis of experimental data. These results show that pulse-like indicator injection best measured values for the model of instantaneous injection in indicator-free flowing groundwater in an infinite strata.
