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.

Supersonic Molecular Beam Injection (SMBI) experiments were performed at GAMMA 10 device under the collaboration with HELIOTRON Group of Kyoto University. In order to survey the effects of SMBI on the plasma behavior, we measured the plasma radiation by using the ultraviolet and visible (UV/V) spectroscopic system and study behavior of the neutral hydrogen and impurity ions emissions with using the collisional-radiative model (CR-model).With SMBI, the neutral hydrogen density calculated by the CR-model was about 20 times larger than that without SMBI. Impurity densities of oxygen ions also increased with SMBI.
