[...] Zooplankton, which get carried by currents, collected in those waters had levels of cesium-137 and the shorter-lived cesium-134 that were on average 40 times higher than the surrounding water, [Nicholas Fisher, a marine science professor at New York's Stony Brook University] said. They also had much higher levels of a radioactive form of silver produced by nuclear reactions. [...]

Fisher said the cesium results were about what researchers expected, but the presence of the radioactive silver was a surprise. [...]
