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.

Fusion plasma engineers have made remarkable progress in designing a tokamak type of experimental reactor, as evidenced by the International Thermonuclear Experimental Reactor (ITER), which produces fusion energy of 1.5 GW(thermal) for 1000 s at least. However, the ITER design is more expensive and requires more advanced technology than earlier machines. With these concerns in mind, extending design options by using a high-temperature superconductor (HTSC) to improve plasma positional instability by placing HTSC ring coils inside the vacuum vessel would be desirable. Here, improving the plasma instability with HTSC coils is discussed, and a possible design of a smaller machine using the coils based on supporting experiments with HTSC tapes is given.
