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 nonfission (NF) heating and thermal-neutron flux were measured in copper as a function of distance from the core center line of the ORR Reactor at different times of a reactor cycle. Above the core, the NF heating is a linear function of the thermal-neutron flux φ expressed by Within the core the relation between the measured thermal-neutron flux and the NF heating is influenced by other factors.
