Officials: Tons of Fukushima radioactive waste in area beyond Tokyo, 150 miles from reactors

Asahi Shimbun, Feb. 1, 2014: Sludge designated radioactive waste for 1st time in Kanagawa — The Environment Ministry has classified 2.9 tons of sludge from Prefecture as radioactive waste derived from the Fukushima nuclear disaster, the first such designation for the prefecture on the southern border of Tokyo. The designation, made in December, means the ministry is responsible for disposing of the radioactive sludge.

[…] As I was photographing workers transferring ash into bags, one worker warned me, “Don’t get too close.” […] Bags of ash covered with plastic sheets formed mountains on the premises. The amount of ash is increasing at a rate of 20 tons a day at the center. Seeing them up close, I felt the ominous weight of the nuclear crisis, which had seemed a distant affair to me up until then.
