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.

It is well recognized that scattered neutrons cause serious image degradation in thermal-neutron radiography of hydrogenous objects. If these scattered neutrons are removed from the neutron beam before it strikes the image record-ing medium, both image contrast and resolution will be enhanced. A method of quantifying the contrast enhancement is illustrated with various antiscatter grid configurations.
