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 tritium recovery system of a fusion reactor, tritium extraction processing from tritiated hydrocarbon is needed. In the present study, a flow-type plasma reactor utilizing capacitively coupled plasma followed by the double tube permeator of Pd-Ag was developed and tritium extraction from tritiated methane in helium was demonstrated. When the helium gas containing tritiated methane was passed through plasma, it was observed that the concentration of tritiated methane decreased and the concentration of HT increased. However, the apparent decomposition rate of tritiated methane was considerably smaller than that of methane. Moreover, the amount of extracted tritium by Pd-Ag was smaller than expected.
