What we do know is of the states highest in the list of cancer averages (within the cancer incubation period after the accident) the ones with similar population density surrounded Pennsylvania, where TMI occurred. New York with roughly 3 times the population, which topped the list, was also in the fall out zone. So it's easy for anyone to say that no-one died because of TMI because there is no gathering of data, no official study, no evidence. It's more honest to say "We don't know how many people died as a result of TMI because because no data was collected".
If you are aware of any such study please provide a link to it.
While I don't have a direct link, Ted Rockwell makes mention of such studies in his blog from time to time. You might be able to contact him for more specifics.
In the post I linked, he writes the following:
And we now know, and have documented, that the type of commercial nuclear plants we have built or planned, cannot, in fact, create a radiological disaster. In 1981, after the Three Mile Island incident, Chauncey Starr, Milton Levenson and others summarized and documented their research on the potential consequences of the worst realistic casualty for commercial nuclear power plants of the type being built in the developed world. They concluded that few if any deaths would be expected off-site.
The research was expanded to a billion-dollar effort, by several nations, over the following decades to the present. After September 11, 2001, with another 20 years of data accumulated, I arranged for 19 nuclear-expert members of the National Academy of Engineering to publish a Policy Forum in the mainstream, peer-reviewed journal Science , updating the 1981 report after TMI, and reaffirming its conclusion that the worst that can be expected is few if any deaths offsite. That conclusion was publicly agreed to by the then-Chairman of the Nuclear Regulatory Commission. The American Nuclear Society White Paper on Realism, followed up with more details, additionally confirming that conclusion. We can no longer claim that radiation is mysterious or uniquely dangerous. The risks of nuclear power are now better understood than most other hazards we face in our daily life.
