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 design window for a liquid metal cooled limiter is being sought to establish the viability of the use of liquid metals as coolants for the limiter. The problem is approached by first establishing the constraints, then defining the geometrical configuration and design parameters, and finally, by analyzing a limiter without coating. The maximum allowable heat flux is found to be ∼ 4 MW/m2. It can be increased to 5 MW/m2 if tapered or insulated feed pipes are used. The presence of coatings required to withstand particle erosion will further reduce the allowable heat flux.
