January 6, 2012 Tepco Press Conference:
Reporter: According to the reading of environmental radioactivity levels as of Jan. 4, 2012, the amounts of cesium-134 and cesium-137 have increased by nearly 10 times from Dec. 27, 2011 to January 2, 2012. I suppose that something went wrong and that led to this increase. What do you think caused this increase?
Tepco Spokesman Junichi Matsumoto: [...] No trouble has occurred during that period. So I suppose that the radioactive materials were blown up by something like wind and that led to that increase.
