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.

Performance of an inertial fusion system for the production of hydrogen is compared to a tandem mirror system hydrogen producer. Both systems use the General Atomic sulfur-iodine hydrogen production cycle and produce no net electric power to the grid. An ICF-driven hydrogen producer will have higher system gains and lower electrical-consumption ratios than the design point for the tandem mirror system if the inertial fusion energy gain ηQ > 8.8. For the ICF system to have a higher hydrogen production rate per unit fusion power than the tandem mirror system requires that ηQ > 17. These can be achieved utilizing realistic laser and pellet performances.
