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.

Materials for potential use in tokamak first wall high current connectors were selected and tested under conditions that might be encountered in tokamak devices. Disk-shaped specimens of promising metal mixtures were subjected to current densities approaching 23 kA/cm2 (150 kA/in2) in 8 ms pulses, closing pressures ranging from .07 to 2.1 MPa (10 to 300 psi), and a vacuum of 1.3 × 10−1 Pa (10−3 Torr). Contact welding occurred at moderate to low pressure and moderate currents. The resulting welds were very weak, failing at 18–31 N (4–7 lb) in shear.
