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 new method is proposed to measure the free volume and the gas content of a pressurized water reactor fuel rod using two expansions of the gas, one at high pressure and the other at low pressure. The gas flow corresponding to these expansions is characterized and modeled. The modeling is then used to prove that this new method is faster and more accurate than the ones usually adopted in hot cells, especially for high-burnup fuel rods.
