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.

An FM reflectometer is developed to measure the density profile of the MP2 device. It operates in the frequency range of 7.78-12.38 GHz. Phase information is obtained by digitizing the IQ detector outputs. However, the measured signal is significantly contaminated by noise due to microwave reflection at various points because the emitting and receiving antennas are installed outside of the vacuum window. A center aligned Fourier transform is used to remove the noise and extract the correct phase information from the measurement. In this paper, data analysis techniques are introducedplasma density profile is shown.
