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.

Based on a simplified transport model, very simple and practical expressions are derived for approximately optimum regionwise importances in a Monte Carlo game with geometrical splitting. Minimum region dimensions where splitting is still efficient are also derived. The proposed expressions show good agreement with results from more advanced theories. Results of realistic Monte Carlo calculations back up the theoretical considerations.
