A researcher at Case Western Reserve University has detected tiny amounts of Iodine 131 from Japan in rainwater collected from the roof of a campus building.
Gerald Matisoff, professor of geology, said the presence of the isotope presents no danger to human health. He estimated the level of radiation is about one-tenth that of natural background radiation.
"In theory, the Iodine 131 could have come from any radioactive waste processing facility," Matisoff said. "But, we know it's from Japan. The isotope is being seen worldwide."
Matisoff and graduate student Mary Carson collect water on the roof of the A.W. Smith Building, on the campus quad, to monitor the particulates being carried in rain into Lake Erie.
Carson ran the analysis Friday and Matisoff verified the findings today.

Some bad news:
At 1:45, the newscaster states that a crane collapsed onto the fuel rods. This is MOX fuel, meaning they damaged rods that contained plutonium.
Plutonium found in soil at the Fukushima nuclear complex heightened alarm on Tuesday over Japan's battle to contain the world's worst atomic crisis in 25 years, as pressure mounted on the prime minister to widen an evacuation zone around the plant. ...
Plant operator Tokyo Electric Power Co said plutonium was found at low-risk levels in five places at the facility, which was crippled by a massive earthquake and tsunami on March 11.
A by-product of atomic reactions and also used in nuclear bombs, plutonium is highly carcinogenic and one of the most dangerous substances on the planet, experts say.
They believe some of the plutonium may have come from spent fuel rods at Fukushima or damage to reactor No. 3, the only one to use plutonium in its fuel mix. ... - reuters
