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.

Particle orbit simulations are carried out to study the ion orbits and loss at the edge of a tokamak plasma. The ion loss conditions are examined as a function of v||/v0 and the distance of ion launching points from the magnetic separatrix. The simulation results are compared with the theoretical ones. Good agreements and detailed features are shown in the simulations.
