years after lawsuit dismissed, debate continues on partial meltdown's
4, 2006 — Ten years ago a judge ruled there was insufficient evidence to
link radiation from the Three Mile Island accident to health problems in
test cases of about 2,000 plaintiffs.
some people who co-exist with the operating nuclear plant continue to
question whether the partial meltdown on March 28, 1979, released
radiation into the environment that has affected their health.

ruling. The rest of the plaintiffs lost on appeal in 2002.
everything about the accident seems to be up for dispute, depending on who
you ask, from how much radiation left the plant, to where it traveled, to
what groups of people might have been affected, to what, if any, health
effects have occurred or might occur in the future.
scientific studies seem to conflict. Some find links to health problems.
Others do not. A new analysis notes more-than-expected cases of thyroid
cancer in York and Lancaster counties over a period of years and pro-
poses - but doesn't conclude - that it could be because of exposure to
radiation from the accident.

debate: No link
studies on the Three Mile Island accident have different conclusions. Some
people even interpret them differently.
the time Columbia University investigators published their findings in
1990 that they saw no link between radiation and cancer cases, the lawsuit
of about 2,000 plaintiffs was under way.
state Department of Health also performed studies. None showed an
increased risk of cancer related to the Three Mile Island accident, said
Richard McGarvey, health department spokesman.
health study showed a higher risk of low-birth weight babies in women who
lived within a 10-mile-radius, but that was determined to be associated
with a higher use of sedatives that appeared to be associated with the
stress pregnant women were feeling, McGarvey said.
the mid-1980s, the state health department updated a registry of 35,000
people who lived within a 10-mile-radius of Three Mile Island, McGarvey
registry of women pregnant at the time of the accident and the children
they bore was updated through the state fiscal year of 1994-95, he said.
Nothing unusual was showing up in the database, so the registry was cut
out of the budget, McGarvey said.
studies of radiological consequences of the Three Mile Island accident
were done by the U.S. Nuclear Regulatory Commission, the Environmental
Protection Agency, what is now the U.S. Department of Health and Human
Services, the U.S. Department of Energy and Pennsylvania, according to the
Nuclear Regulatory Commission.

increases in cancer cases, he said.
Alfred Wilcox of Pepper Hamilton LLP in Philadelphia represented the three
power companies and their parent company, GPU, that the about 2,000
plaintiffs sued. Rambo's decision should give comfort to anyone concerned
that the radiation adversely affected their health, Wilcox said.
plaintiffs' case fell apart with their complicated theory that a blowout
of radiation from the reactor avoided all of the detection monitors and
huge doses hit pine and spruce trees and people, Wilcox said.

say the accident presents a unique opportunity for continued study.
Talbott, a professor of epidemiology at the University of Pittsburgh, said
that, even though exposures during the accident were low, the population
should continue to be followed. That might be possible using the state
health department's cancer registry, she said.
one of her studies, a 20-year follow-up of mortality, published in 2003,
Talbott used information from the state's registry for residents who lived
within a five-mile radius of Three Mile Island, combined with the state's
mortality data. The study found radioactivity released during the nuclear
accident did not appear to have caused more cancer deaths in residents
between 1979 and 1998, Talbott said.

exposure in the days after the accident, but that trend appeared to weaken
between the 1992 and 1998 study updates, she said.

reviewing state Department of Health data, a Harrisburg-area doctor found
more thyroid cancer cases than expected in York County for every year
except one between 1990 and 2002.
Roger Levin, a head and neck surgeon who has experience treating thyroid
cancer, said one reason for the higher incidence of thyroid cancer could
be that people were exposed to radiation during the TMI accident.
thyroid - a gland in the neck - controls the body's overall metabolism. It
manages weight, pulse rate and body temperature.
the thyroid needs iodine to make its hormone, it's possible the gland
could have taken in more radioactive iodine during the accident, Levin
said. The gland cannot distinguish between radioactive iodine and the type
found in table salt, which is why the state passes out non-radioactive
iodine pills. In theory, people could take the pills during a nuclear
accident to fill up the gland to protect it.
the increased cases in York and Lancaster counties, Levin said,
radioactive material could have traveled to those counties by water, since
it seems the wind was not blowing in that direction during the accident
and days after.
Levin started his research, he expected to see no difference in the number
of thyroid cancer cases expected and the number reported in area counties.

study was conducted on behalf of the about 2,000 plaintiffs who claimed
emissions of radioactive gases during the Three Mile Island accident were
much larger than the industry and government stated and that intense
plumes had exposed small areas to high radiation doses, resulting in
adverse health effects, including cancer.
Wing's research found positive relationships between accident dose
estimates and cancer rates for leukemia, lung cancer and all cancers
combined. The study looked at the difference between the pre-accident
