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.

Decay ratio was estimated via a simplified method from the impulse response function that had been evaluated using a univariable autoregression method. Suggested estimation was utilized in neutron noise measurements carried out during seven fuel cycles of a 1300-MW(electric) pressurized water reactor. Results show that such an evaluation method can be used to monitor the increasing oscillation of the neutron flux during the fuel cycle.
