Gov. Tom Corbett is about to discuss rainwater testing in Pennsylvania and other states that shows very low concentrations of radiation, apparently from the Japanese nuclear plant damaged by an earthquake and tsunami.
Corbett and the heads of the state departments of Environmental Protection and Health plan to talk about the results of the tests at a noon news conference Monday in Harrisburg.
In Massachusetts, officials said Sunday that one rainwater sample registered very low levels of radiation from radioiodine-131, which is short-lived. They said it posed no threat to drinking water or public health.
More than 100 samples were tested nationally through an Environmental Protection Agency network. Massachusetts officials said similar testing in California, Pennsylvania, Washington and other states showed comparable levels of I-131.
