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 prediction of electromagnetic loads on blanket module 1 of the ITER device during a plasma disruption event is considered. This analysis is performed for a number of design variations (of the blanket module) and different disruption events.The key features of the analysis procedure will be presented including the geometric description of the blanket module composed of a first wall, shield block, and vacuum vessel. The modeling of the plasma current will also be described.The electromagnetic analyses are performed using the Opera-3d software. The transient eddy currents are first calculated, from which the electromagnetic loads are determined. Once these loads have been calculated they can also be exported for additional post-processing to assess the mechanical loading effects.
