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 behavior model for fission gas in irradiated liquid-metal fast breeder reactor fuels is applied in a computer code. The subroutine LANGZEIT calculates the “long-time” kinetics processes during steady-state operation. The results are used as initial conditions for the subroutine KURZZEIT, which permits the description of the bubble growth during rapid overpower transients. This model has been applied to the SNR-300-Mark I core. The calculations indicate a prompt precipitation of fission gas during the reactivity excursions, which results in a dampening effect on the reactivity ramps.
