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 composite containment proposed aims to cope with beyond-design-basis accidents. The goal is to restrict the consequences of severe core meltdown accidents to the reactor plant. One essential of this new concept is passive decay heat removal from the containment by natural air convection. Experimental and calculational results obtained up to now with the passive containment cooling program suggest that in the composite containment of a 1300-MW(electric) pressurized water reactor, the decay heat can be safely removed by natural air convection. Detailed experimental investigations and large-scale tests envisaged will complement the results and provide the database for the design of the containment and further development of multidimensional computer codes.
