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.

To provide a technical basis for improved in-service inspection (ISI) plans, Pacific Northwest Laboratory (PNL) has developed and applied a method that uses results of probabilistic risk assessment to establish piping system ISI priorities. In the PNL program, the feasibility of generic ISI guidances is being conducted in two phases. Phase I identifies and prioritizes the systems most relevant to plant safety. These evaluations lead to the development of comprehensive ISI guidances for pressure boundary systems and components that take place in Phase II.
