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 shielding properties of ilmenite-magnetite (I-M) concrete are measured experimentally. The instantaneous relaxation length and thickness-dependent removal cross section of neutrons from a 252Cf source penetrating I-M concrete with and without a cadmium sheet are reported. An empirical formula is developed to calculate the thickness dependence of the removal cross section and the related coefficients are reported. The results illustrate the effectiveness of I-M concrete so far as its shielding properties are concerned. This material can be used to shield reactors, accelerators, X-ray installations, and radioactive sources used for commercial purposes.
