Nuclear Power

This photo shows the Berkeley 60-inch cyclotron, build in 1939. The year before, technetium-99 was discovered by Emilio Segrè and Glenn Seaborg using the facility's 37-inch cyclotron. Ernest Lawrence, the cyclotron's inventor, is standing, third from left.

Old Particle Accelerator Tech Might Be Just What the Doctor Ordered
