'Few in the mainstream media are talking about it these days, but radiation from the Fukushima Daiichi nuclear disaster is still spewing into and contaminating the environment. And a professional engineer from Worcester Polytechnic Institute's (WPI) Department of Civil & Environmental Engineering says that levels of radioactive cesium in US topsoil have recently been detected at levels up to 10,000 percent higher than previous studies have found.

Marco Kaltofen, PE, has been investigating nuclear material release as part of his dissertation, entitled Radiation Exposure to the Population in Japan After the Earthquake. And samples of US topsoil he recently collected and analyzed revealed levels of radioactive cesium up to eight nanoCuries per kilogram (nCi/Kg), which is about 10,000 percent higher than levels previously assumed in a study by the University of California, Berkeley (UCB).'
