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.

Light water reactors (LWRs) are expected to be a primary source of electrical power in Japan into the 21st century. A next-generation LWR must be developed that efficiently uses uranium resources and improves fuel economy. A high-conversion boiling water reactor (BWR) core design is proposed that conserves natural uranium through a high conversion ratio that is achieved through efficient utilization of the vapor void in the BWR core. The proposed reactor concept employs fuel bundles with a square channel box and cruciform control rods, which are commonly used in conventional BWRs. Thus, it is possible to use current BWR core internals and vessel designs with minimal modifications, which makes the entire reactor system design more feasible.
