Baxter Black's Thoughts on Radiation

The destructive potential of radiation is only matched by the naiveté that people had when handling it. During the fifties, radiation and radioactive materials were dealt with in ways that would horrify anyone today. Radium was used to make watch faces glow-in-the-dark, and hand-painted by workers. Many licked their brushes to wet them, and later perished from agonizing throat and mouth cancer. Uranium was placed in golf balls so they could be located by giger counters when lost in the woods. Frank Zappa's doctor injected a radium insert into his nose when he was a child, to combat his nasal infection.
It's no wonder there's so many radioactive zombies.
