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.

This paper describes a concept for a high performance, inherently safe fusion reactor blanket using helium coolant, beryllium multiplier, lithium breeder and a vanadium alloy structure. The goals of the design were to explore the possibility of inherent tolerance to loss of coolant and flow accidents while minimizing the cost of electricity. Results indicate high net thermal-to-electric conversion efficiency (45.5%), good energy multiplication (1.64) and excellent afterheat tolerance, with a maximum blanket temperature of 760°C after one year with no cooling. However, the calculated COE (0.0405$/kWe.h) is slightly higher than other blankets costed on a similar basis by the MINIMARS1 program because of the projected high cost of vanadium.
