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.

Two suggestions are put forward for avoiding numerical difficulties encountered in the treatment of optically thick media by analytical methods such as Lie series. One is the usual procedure of subdividing a single zone into several subzones. The use of Lie series in connection with this formalism is described. The second method allows a coarser subdivision of a given zone but is restricted to plane geometry.
