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.

Modern predictive simulations have a special focus on the systematic treatment of input, model and data uncertainties and their propagation through a computational model to produce predictions of Quantities-of-Interest (QoIs) with quantified uncertainty. Although the modeling of nuclear reactors has made tremendous progress, there are always discrepancies between ideal in silico designed systems and real-world manufactured ones. As a consequence, uncertainties must be quantified along with simulation to facilitate optimal design and decision making, ensure robustness, performance and safety margins. This workshop will provide an overview of the fundamental concepts in Uncertainty Quantification (UQ) and Sensitivity Analysis (SA), as well as comparative reviews of forward/inverse UQ and SA approaches. Topics on quantifying prediction uncertainties in Machine Learning models will also be briefly covered.
