First of all, it is not at all clear that workers at Fukushima have not died. Read the article: Contract workers registered with TEPCO have mysteriously disappeared from the contractor’s employment records. Mainichi: "Whereabouts of 30 nuclear power plant subcontractors unknown: Health Ministry"
Second, there is considerable evidence of ongoing fission at the Fukushima plant reactors given the ongoing production of Iodine-131, which has a 8 day half life. See Gunderson’s Fairewinds updates http://www.fairewinds.com/ and Washington’s blog for an essay with citations on ongoing criticality http://georgewashington2.blogspot.com/2011/06/are-nuclear-reactions-still-occuring-at.html
Third, spent-fuel pool #4 is an ongoing cataclysmic disaster. Building #4 was damaged by #3’s explosion and the spent fuel pool in #4’s attic was reported by the NYT to be cracked. This pool is full of rods and is leaking water and was recently found to be 2/3 empty, meaning there was a high likelihood that the fuel rods were exposed. http://www3.nhk.or.jp/daily/english/20_03.html
Fourth, de-contamination of the radioactive water has not gone well and has had to be stopped over and over because of various problems
Fifth, radiation releases continue to be very large
“Estimates of the radioactive materials emitted double doors opening to the Fukushima No. 2 unit building $ 1.8 billion becquerels”
DISREGARD INDUSTRY TROLLS AND DEMAND TRUTH, TRANSPARENCY AND ACCOUNTABILITY
