Pacific nuclear waste dump at threat from rising sea levels

Rising sea levels are bringing new worries about a nuclear waste dump in the Marshall Islands, about 5000km north of New Zealand. In the late 1970s, Runit Island, on the remote Enewetak Atoll, was the site of the largest nuclear clean-up in United States history. Radioactive material from atomic weapons tests in the 1940s and 50s was dumped into a 100-metre wide bomb crater and then covered with concrete. Locals call it the Runit Dome, and tests have shown it is still highly radiocative. Joining us on the line now from the city of Majuro in the Marshall Islands is the country's Red Cross Secretary-General Jack Niedenthal.
