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 dynamic model of the Gas Turbine-Modular Helium Reactor core has been developed using the Simulink simulation program. The Simulink model utilizes a space-independent neutronics (point-kinetics) model along with a space-dependent heat transfer model of the core to simulate the short time reactor transients. The core model employs unique capabilities of the Simulink program to implement a user-friendly fully interactive environment to perform a variety of reactor transient scenarios.
