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 effect of halogen plateout sources on containment post-loss-of-coolant accident dose rates has been evaluated. The main approach utilized has been to compare the dose rates due to halogen plateout and halogen immersion (or atmospheric) sources, assuming each is comprised of an equal inventory of radioiodines. Based on the parameters chosen, including the use of only the primary 131I photon, 0.36 MeV, for all calculations, the gamma-ray dose rate from the atmospheric component will always dominate over the plateout component for full containment configurations. However, for small chambers within the containment, the atmospheric and plateout dose rates are relatively comparable, so that determining which is greater depends on the location of the dose point.
