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.

This paper shows that the design improvement of the ECH antenna system for high efficient heating of GAMMA 10 tandem mirror plasma. The previous ECH antenna was not large enough to cover the microwave because it was limited by the port size. New antenna system clears this limit and is enlarged as large as possible. And its size becomes twice, which enables to inject the microwave with the efficiency up to 95%. It is about 20% increase as compared with the previous system.
