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 experimental study of liquid metal tokamak limiters was undertaken in Russian T-3M and T-11M tokamaks (Ip 100kA BT [is approximately equal to] 1T) between 1990-2004. In T-3M droplet stream and film flow Ga limiters were tested. In T-11M the experiments with Li Capillary Pore Systems (CPS) as rail limiter for investigation of real Li erosion in typical tokamak boundary condition (Te = 30 ± 10 eV, Pload = 10 MW/m2, D, He plasma) were performed. It was shown, that use of a liquid metal as material of tokamak limiter has not a serious physical obstacles.
