Radiation has a sneaky way of spreading, and in Tokyo, citizens have identified 20 sites contaminated by radioactive cesium from the Fukushima meltdown.
The government wasn't planning on testing in Tokyo, but citizens and a nuclear research center started their own investigation and came up with positive results.
Here's the response the city's head of health and safety gave the New York Times about the results: "Nobody stands in one spot all day…And nobody eats dirt." Also, radioactive material probably fell on concrete and got washed away! Nothing to worry about!
Not particularly reassuring, especially given the Japanese government's record on this accident.
