Searching for radioactive waste in the depths of the Atlantic

For nearly five decades, more than 200,000 barrels of radioactive waste were dumped in the icy depths of the northeast Atlantic. Today, no one knows precisely where these barrels are located, or what kind of state they are in. On June 15, a French-led team of scientists will set sail from Brittany in a bid to map the barrels and assess their impacts on surrounding marine ecosystems.
