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.

Solutions are obtained for the concentration of radioactive nuclide on the walls and in the radially mixed fluid transporting the nuclide, when the fluid circulates in a closed loop system. The differential equations, which describe the mass balance of the nuclide in the system and on which the solutions are based, take into account nuclide sorption-desorption on the system walls (at constant rates) and a source which releases the radioactive nuclide (fission product) into the stream.
