It's still unclear if the Japanese nuclear plant that exploded this morning is experiencing a meltdown or not. But it definitely is leaking radiation: Three out of 90 people tested in the town of Fukushima "show excess exposure to radiation," reports the Los Angeles Times. "The people had apparently been exposed as they waited outside a school for evacuation by helicopter."

Even as they evacuate 50,000 people from a 12 mile area around the plant and flood the reactor with seawater to cool it, Japanese officials say there's no risk of a Chernobyl II.
