The World's Most Radioactive Places

Hanford Nuclear Reservation Site | Hanford, Washington

The site was a nuclear production complex built in 1943 as part of the Manhattan Project. In the decades that followed the Hanford Site saw the production of plutonium for the majority of America's 60,000 nuclear weapons. Although it has since been decommissioned, the area is still home to a huge amount of nuclear waste - it will take decades to decontaminate.
