EPA: Boise Rainwater Has Highest Levels of Radioactive Material in US, 80 Times Amount of I-131 Allowed in Drinking Water

EPA: Boise Rainwater Has Highest Levels of Radioactive Material in US, 80 Times Amount of I-131 Allowed in Drinking Water: "Elevated levels of radioactive material in rainwater have been expected as a result of the nuclear incident after the events in Japan since radiation is known to travel in the atmosphere – precipitation data collected by EPA in the states of California, Idaho and Minnesota have seen elevated levels of radiation in recent precipitation events.

In all cases these are levels above the normal background levels historically reported in these areas. While short-term elevations such as these do not raise public health concerns – and the levels seen in rainwater are expected to be relatively short in duration – the U.S. EPA has taken steps to increase the level of monitoring of precipitation, drinking water, and other potential exposure routes to continue to verify that."
