Episode notes
Lake Karachay Is A Secret Nuclear Wastesite
- Lake Karachay was a secret Soviet nuclear waste dump that became possibly the most polluted place on Earth.
- Government researchers traced Arctic radiation back through a river to the sealed plant and the contaminated lake beside it.
Explosion, Dust, And Concrete Burial
- In the 1950s a tank explosion at the plant released nearly as much radioactivity as Chernobyl and later droughts exposed contaminated lakebed dust.
- Officials later filled the drying, poisoned lake with 10,000 concrete blocks, then covered it with rock and dirt to bury the waste.
Danger Turned Into Cultural Myth
- Lake Karachay transformed from an ordinary Ural lake into a place so radioactive that an hour on its shore could be fatal.
- Its extreme danger and secrecy turned the site into a potent imaginative vessel for artists and writers.
