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.

The high power RF transmission components are developed for transmitting MW level of RF power continuously in ICRF heating and current drive system. A water-cooled co-axial transmission line with the special connector for water sealing while maintaining electrical contact, a vacuum feedthrough of 1 MW RF power which. has two alumina (Al2O3, 97%) ceramic cylinders and O-ring seal instead of a brazed seal for good mechanical and thermal strength, and the phase shifter using liquid instead of gas for insulating dielectric medium were developed. RF tests show that stable operation is possible with the peak voltage over 30 kV for 300 seconds.
