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 high power gyrotron is designed and tested. The design is based on the TE31,8 1 MW gyrotron. The higher power design is realized by choosing TE31,12 higher order oscillation mode. A basic test of the high power gyrotron is performed in JAEA test stand with short pulse and long pulse. In the short pulse experiments, 1020 kW output is confirmed with expected output beam pattern. In the long pulse experiments, it is successfully achieved stable 1 MW operation (1030 kW/2 s). The longest shot is 550 kW/~200 s. These results show successful design and fabrication of the TE31,12 high power gyrotron.
