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.

In the current study, investigations are reported on the effect of pressure gradients on the optical properties of the window used in optical diagnostics of plasma. Window surface deformations due to pressure gradients (differences between the inside and outside pressures of a vacuum vessel) at the vacuum interface are monitored with a digital dial gauge. The effects of these surface deformations on laser beam propagation through the window are discussed in the context of optical diagnostics. Ultra-high-vacuum sealing of a large rectangular glass window with a metal assembly using a Helicoflex seal is also discussed.
