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.

A simple, analytic approximate theory has been developed for calculation of x-ray transport in one-dimensional Cartesian geometry. The form of the theory is particularly suited to numerical computation. Deposition and energy currents can be calculated in times comparable to those required by exponential mass-absorp-tion codes, with accuracies comparing favorably with more sophisticated discrete ordinates or Monte Carlo calculations. Although the theory is presented in terms of x-ray transport, it should be applicable to any transport problem for which (a) scattering is not highly anisotropic, and (b) averaged cross sections may be defined for secondary particles.
