[…] 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.
