Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

A fast electron loses kinetic energy as it passes through a medium by an amount that depends, among other things, on the distance traveled in the medium. This energy spectrum of electrons has been measured as a function of the distance. In this experiment, the spectrum has been empirically determined using water as the absorption medium. The feasibility of applying the method to other media is also demonstrated.
