In 1985, nuclear chemist Galen Winsor shocked many by eating uranium to prove it wasn’t as dangerous as believed. He worked with radioactive materials for over 30 years and wanted to challenge public fear. Amazingly, he lived another 23 years and died at age 82 in 2008.

His cause of death was never revealed, but experts today agree that uranium is toxic. “The kidneys are most affected by uranium exposure,” studies show. Even though it’s radioactive, the main danger comes from its chemical toxicity.

People who inhale or swallow uranium may suffer kidney damage, especially from water-soluble forms. Breathing in insoluble uranium can also affect the lungs.

Animal studies have shown mixed results. Some report behavior changes and lower fertility, while others don’t. Skin exposure to certain uranium compounds has caused irritation in tests.

Winsor’s survival doesn’t mean uranium is safe — just that very low doses may not be instantly fatal. Experts strongly warn against any direct contact or consumption.
