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 general theory of reactor noise in the time domain for a zero-power reactor is formulated by using an equation for the probability generating function (pgf). With suitable manipulations of the pgf, several previously known theoretical results from noise analysis in the time domain can be deduced from this general theory. Although the detection process is not treated generally, a new result is the explicit determination of the pgf for the case where delayed neutrons are considered.
