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 neutronics and photonics of the gas-carried Li2O blanket have been studied. The blankets studied consist of 20 to 30% Li2O solid particles and 2% Type 316 stainless-steel structural material in volume. The Li2O blanket can achieve a high tritium breeding ratio without a neutron multiplier due to its high lithium atom density. The effects of the design variations on the tritium breeding ratio and total nuclear heating are summarized as follows:
