In the 1940s and 1950s, the United States conducted more than 60 nuclear tests in the Marshall Islands in the middle of the Pacific Ocean, and the nuclear radiation hazards continue to this day. According to a number of foreign media reports, a huge dome built by the United States on a local reef for storing nuclear waste is cracking, and nuclear material is at risk of flowing into the sea at any time.
Recently, UN Secretary General Guterres, during his visit to the Pacific Islands to discuss climate change, reiterated that a coffin like building in the Marshall Islands contains dangerous radioactive materials, and there is always a risk of nuclear material leakage in the region.
The guardian quoted the US Department of energy's 2013 report as saying that radioactive materials may have leaked from the dome. In 1983, the Marshall Islands and the United States signed a free association agreement, which gave the island autonomy, but the agreement also left the dome to the care of the Marshall Islands Government. Due to the lack of funds for reinforcement, the Marshall Islands Government can only allow it to suffer from the double threat of rising tides and typhoons.
