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 background deuterium neutral gas pressure is a major operational parameter affecting the physics of the ionized gas discharge in the inertial electrostatic confinement (IEC) axial-cylindrical fusion neutron generator device (C-Device). There is uncertainty in its actual value in previous experiments. The cylindrical hollow IEC modeling program (CHIMP) computer code is a particle-in-cell, Monte Carlo-collision (PIC-MCC) model that includes ionization and secondary electron emission processes and is used to give preliminary results for the ionized gas physics behavior and neutron generation in the C-Device for a range of pressure calibration factors.
