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 technique has been developed for detecting defective SiC layers in silicon carbide-pyrolytic carbon coated fuel particles. The outer coating of carbon is burned off at 800°C, and the particles are pressurized at 1000 lb /in.2 in a mercury porosimeter. Mercury is forced through any defects in the SiC layer and into the porous carbon. The particles are examined by a low-voltage microradiographic technique. Defective particles were detected in some batches of coated fuel particles.
