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.

In the tandem mirror GAMMA 10, a 500 kW gyrotron was newly equipped in the central-cell ECRH system, following the plug ECRH systems. Then, the transmission system for the central-cell ECRH, including a taper, mirrors and a polarizer, has been designed correspondingly. The guidelines to design the transmission system are to make the beam cross section axisymmetrical on the resonance surface with a high power transmission rate and high heating efficiency. According to the guidelines, mirrors in the launcher systems have been designed with our electromagnetic code. Controlling polarization of the incident microwave is achieved with a polarizer for raising heating efficiency.
