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.

Changes in in-core self-powered neutron detector signals, recorded during a nuclear loss-of-coolant accident (LOCA) simulation, have been correlated with liquid level changes that occurred during the core uncovery and recovery events. The correlations indicate that these detectors can be used to monitor reactor vessel liquid level during a LOCA. A display and alarm system using these detectors to provide reactor operators with an indication of a core uncovery and subsequent thermal excursion and with a means to measure the effectiveness of LOCA recovery procedures is described.
