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.

In Part A a procedure is described for calculating neutron fluxes at nodes of a three dimensional grid with few points in planes perpendicular to a selected axis. Difference equations relating fluxes within each plane are determined in advance from detailed two dimensional studies. This “multichannel synthesis” model may be used for parameter studies and dynamic analysis. Comparison of a representative calculation with results of a detailed three-dimensional computation is given in Part B.
