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.

Reliable and safe operation of a nuclear power plant or any other complex network of flow-connected subunits requires prompt detection and location of failed subunits. An algorithm is described, which performs (in many cases) unambiguous automatic location of single or multiple failures. Types of failures that cannot be located unambiguously are characterized. The algorithm can be applied to networks with a serial array of subunits, with converging or branching nodes or with feedback. An optimal structure of the algorithm is identified that allows the maximal failure locating capability with a minimum of logical or arithmetical manipulation. This is important especially for application to large systems. The dynamic behavior of the algorithm is examined for a simple system.
