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.

Evaporation of sodium from components using heat and vacuum was investigated as a method of sodium removal from liquid-metal fast breeder reactor components. The method was determined to be capable of efficiently cleaning components at temperatures as low as 260 to 315°C and at pressures of ∼1 × 10−3 to 1 × 10−4 Pa. The most rapid cleaning was observed with small crevices, where the sodium is expelled by gases released from the sodium. The method was recommended as a viable process that should be investigated using full-size components.
