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.

Recent concern of possible deterioration in the dynamic response of safety-related sensors has led to broadened U.S.. Nuclear Regulatory Commission requirements in periodic testing. Time response checks must now extend through the entire protection channel, including the sensor element. To accommodate this requirement, a testing unit and test methodology were developed to permit practical in-situ response measurement for pressure and differential pressure transducers. Comparison tests were made against Statham strain gauges and a representative sample of pressure sensors in commercial use. These tests served to validate the test approach and also to characterize dynamic behavior of sensors employed in safety applications. Supplementary investigations of test accuracy and potential sensor-line effects were performed.
