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 method of singular eigenfunction expansions is applied to time-independent one-speed problems in which there are two half-space media which scatter neutrons anisotropically. Integrals are derived which reduce the calculation of the expansion coefficients to the solution of a non-singular integral equation plus associated coupled equations. In general, none of the expansion coefficients are found in closed form.
