Radioactivity detected from 71-year-old nuclear tests by US
US-based researchers have found lingering radioactivity in the Pacific's Marshall Islands where the US conducted 66 nuclear tests from 1946-1958, and three islands from Bikini and Enewetak Atolls were "bombed out of existence". The team reported plutonium levels to be 100 times higher in lagoon waters compared to the surrounding Ocean while caesium levels were also twice than normal.
