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 thermal probe method is capable of measuring ion temperature using the heat flow from plasma (Qplasma) versus the bias voltage (Vp) characteristic. Considering the heat transition phenomenon in the probe, we designed the thermal probe in order to obtain the Qplasma-Vp as well as the Ip-Vp characteristics. We performed a preliminary experiment of the thermal probe measurement in the divertor simulator MAP-II, and discuss the results and the assignments of the thermal probe method.
