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.

A high-enthalpy plasma facility with 0.4 MW power level has been constructed at Chonbuk National University in Korea. A segmented arc plasma torch was adopted as a plasma source for this facility. It is designed to have high thermal efficiency and long life in the production of supersonic plasma flow with enthalpy above 13 MJ/kg at a velocity of Mach 3. Diagnostic systems include enthalpy probe with mass spectrometer for the measurement of enthalpy, plasma composition and plasma temperatures, and heat flux probe for the measurement of heat flux. Visualization systems such as a pyrometer, a fast camera and an emission spectroscopy have been installed to monitor the surface temperature of the substrate, the plasma density and flow patterns.
