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.

We proposed a flexible electron density measurement system based on the interferometer for confinement study. An INRD guide antenna for spatial scan capability of a probe beam has been analytically designed. As a result of fabricating and evaluating the antenna, it was confirmed that the antenna has a predicted performance. We also evaluated the analysis method of a sampled data with numerical simulation in order to calculate phase shift due to the plasma density. A 3000 order FIR filter could successfully separate a sample signal with various frequencies into a signal with a single frequency when S/N is not critical.
