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.

The purpose of this paper is to compare the characteristics of operator behavior in a conventional and an advanced MCR (Main Control Room) under a simulated emergency and to describe different operation characteristics and common operation characteristics of operators in the analog and digital environments. To this purpose, we compared the operation characteristics from a task point of view including ‘checking/verifying process parameters’, ‘component manipulation with device control’ and ‘operation by operator’s knowledge’. Based on the results, in an advanced MCR, opportunities to successfully cope with a given scenario have increased due to design characteristics of digital environment and operator’s simultaneous cross checking.
