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 direct energy conversion system designed for D-3He fusion reactor consists of a CUSP direct energy converter (DEC) and a Traveling Wave DEC, where, respectively, electrons and thermal ions are separated from fusion protons and decelerated via Venetian blind type electrodes to produce DC power, and protons are velocity-modulated, bunched, and then decelerated by RF traveling waves to produce RF power. For the basic investigation of the CUSPDEC, a small scale experiment is conducted using a device consisting of a single cusp and low-energy plasma and ion sources. Performed are the measurements of basic characteristics of the behavior of charged particles in various conditions including magnetic field gradients, spatial locations of incidence, ion masses, and ion energies.
