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 liquid metal facility using the eutectic composition of sodium and potassium (NaK) as the working fluid has been designed and constructed at The University of Texas at Austin. The facility is capable of experimentally modeling magnetohydrodynamic flow through many of the geometries envisioned for fusion related systems, particularly blanket designs. A study currently in progress involves the measurement of the magnetohydraulic pressure drop across a packed bed of electrically conducting spheres. Reynolds numbers based on volume flow rate and sphere diameter range from 5 to 300, and Hartmann numbers range from 0 to 200, resulting in an interaction parameter range up to 4000.
