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 Parasite Reactor is a 1-liter pressure bomb for phase studies under irradiation at temperatures and pressures up to at least 400°C and 5000 psi. Provision was made for sampling of solid, liquid, and gas phases for analysis. Power output was measured. Yields of radiolytic gases were calculated. It was established that uranyl nitrate solutions are sufficiently stable up to 248°C to be used for a proposed high-pressure Water Boiler reactor.
