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 development of radiation-resistant materials to sustain the harsh fusion environment represents a challenging task for divertor designers. In recent years, advanced physics simulations of the power leaving the plasma with radiation and charged particles indicate much higher heat fluxes to the divertor than previous estimates. In response, experts in EU, Japan, and US developed several W alloys for advanced He-cooled divertors that can handle heat fluxes in excess of 10 MW/m2. This paper briefly discusses the ongoing effort to develop W alloys suitable for fusion applications, the challenging phenomena impacting the behavior of W under a fusion environment, and the environmental impact of the most promising, state-of-the-art alloys: W-La2O3 and W-1.1TiC.
