Navajo people poisoned by uranium mining have been fighting for decades for restitution

The Diné helped dig the raw materials to build the US’s nuclear arsenal, but were never told of the danger

Allen Tsosie was just 14 when he went to work in the uranium mines in the Lukachukai mountains near Cove, Arizona.

Tsosie was one of thousands of Navajos who took jobs in the mines, starting in the 1940s. They worked without masks or ventilation to disperse the lethal radon gas, and they were never told the rocks they were handling – leetso in the Diné language, or yellow dirt – were deadly.
