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 Japanese design of HFTM, so-called HFTM-H, aims to be used for high temperature irradiation test up to 1000°C for SiC/SiCf composite and refractory materials. During irradiation test periods in the IFMIF, irradiated materials must be maintained at constant temperatures. It is confirmed that the conceptual design of HFTM-H can satisfy the requirement for displacement per atom (dpa). The gas production rate to dpa ratio, which is important requirement for the design of HFTM-H as well as dpa is calculated. Nuclear heating distribution in HFTM-H is also predicted, which is served to temperature control design and structural analysis.
