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.

Using energy from a fusion reactor to produce such synfuels as hydrogen is a challenging goal because of the special thermal requirements imposed on the blanket design. The interfacing of the tandem mirror reactor to the General Atomic thermochemical process (TCP) for hydrogen production considering two types of interfacing approaches is investigated. The first uses electrical energy to joule heat a high-temperature part of the TCP and can have an overall plant efficiency of ∼30 to 36%. The second approach uses high-temperature thermal energy to heat the high-temperature part of the TCP and has an overall plant efficiency of 43%. The trade-off between these two approaches involves consideration of overall plant efficiency versus the feasibility of developing a cost-effective, high-temperature blanket and heat transport system for long lifetime and high reliability.
