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 magnetically stabilized fluidized bed nuclear fission reactor (MSFBR) concept is proposed. A large number of fuel particles with 1 mm diameter containing ferromagnetic material are floated in the reactor core by balancing the gravitational force and the drag force of helium coolant flow. Superconducting solenoid coils produce magnetic fields inside the reactor core. Advantages of the MSFBR concept are its excellent heat transfer property from the fuel to the coolant and improved safety, while the bed is stabilized by the magnetic force, contrary to previous fluidized bed reactor concepts.
