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 computational code for designing the resonant cavity of a gyrotron has been developed to design new gyrotrons for the future GAMMA 10(PDX). The developed code calculates the cavity RF profile function by simultaneously solving a set of relativistic single-particle equations of motion and wave equations to obtain a self-consistent solution in the dynamic system that accounts for the effects of the electron beam on the cavity field profile. Beam-wave interactions mainly occur in the uniform middle section of the resonator. The calculation results explain well experimental data of the gyrotron used in GAMMA 10 ECH system.
