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.

A method of studying the burnup of high-cross-section materials in nuclear reactor control rods by neutron radiography is described. The technique has been applied to the examination of the burnup pattern of a CP-5 reactor control rod and has been found to provide a detailed picture of the burnup pattern, showing a very sharp transition region. The radiographic study has been made by a comparison method in which the neutron transmission of the irradiated cadmium control material has been compared to that of normal cadmium. In the regions in which the cadmium control material has been highly depleted in Cd113, the equivalent normal cadmium thickness comparison can be made to an estimated accuracy of 0.0006 inch.
