New York Times: The Comprehensive Test Ban Treaty Organization, a Vienna-based arm of the United Nations, has released a forecast of where and when the winds blowing over Japan will carry the radiation emanating from Japan’s tsunami-stricken nuclear reactors. The forecast predicts that the radiation plume will reach the Aleutian Islands today and Southern California late tomorrow. As the New York Times‘s William Broad reports, the UN forecast does not specify how much radiation will reach the US, but the level is expected to be harmless.
