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 neutron total cross section of U233 was measured from 0.07 to 10,000 ev, using the ORNL fast chopper time-of-flight neutron spectrometer. Below 30 ev the neutron energy resolution varied from 0.7 to 1.5% and above 30 ev it was 60 nanosec/meter. A description is given of the measurements, the samples, and some of the errors in the measurements. The errors on the total cross section data are estimated to be from ±0.6 to 1.1% below 1 ev, from 1.1 to 2.5% between 1 and 100 ev, and from 1.5 to 5.5% above 100 ev.
