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 use of 6LiT pellet injection for the Burning Plasma Experiment (BPX), the International Thermonuclear Experimental Reactor (ITER), or reactor fueling using the low ion temperature catalyzed reaction 6LiT + D-D proposed by Krasnopol'skij et al. is investigated. Solid LiT has significant advantages as a pellet material over cryogenic deuterium-tritium because of its higher heat of sublimation, mechanical strength, attainable pellet velocity, and plasma penetration. The implications of this for ignition scenarios are discussed. Injection of LiT has the additional advantage of inherent lithium wall conditioning, which has been shown in the Tokamak Fusion Test Reactor (TFTR) and the Texas Experimental Tokamak (TEXT) to have effects similar to boronization. The injection of LiH pellets has been demonstrated in TEXT, and observed pellet penetration is compared with an ablation model, which is then used to predict LiT penetration in ITER and BPX.
