A few months ago it was reported that waste incinerators (which is how Japan handles its trash) were finding high levels of radiation in the ash of the burned trash.  The disaster at Fukushima Daiichi was blamed.

Today, waste incinerators as far south as Tokyo are still emitting cesium through their exhaust stacks.  One incinerator in Edogawa ward registered 9,740 becquerels of cesium per kilogram!  The incinerator handles only household trash.  This is an indicator that cesium is still being spewed into the air, and it’s settling as far south as Tokyo.
