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 problem treated in Part I in terms of a continuous µ-variable is here treated in the double-PN approximation for azimuthally symmetric situations. Exqplicit representations for basic matrices are derived. The transfer matrix equations were solved on the CDC-6600. Results are presented for two problems of interest—transmission and reflection from thick slabs and the finite reflector critical problem. Anisotropic scattering is considered in both cases. Tables of typical computing times are presented.
