Introduction

In the study summarized here, we tested the hypothesis that the risk of certain cancers 
might have been raised by exposure to airborne radiation from the Three Mile Island 
nuclear power plant, which had a widely publicized reactor accident early on the 
morning of March 28, 1979. Monitoring equipment was limited but, based on 
available measurements, dosimetry experts stated that the average exposure to 
individuals living near Three Mile Island was in the range of 0.1 - 0.25 mSv (that is, 
0.01 - 0.025 rem). According to these estimates, exposure from accident releases was
a fraction of the average yearly exposure from natural background radiation (about 
0.8- 1 mSv, or 0.08-0.1 rem). Official reports predicted that among those within 50 
miles of the Three Mile Island facility, at most one cancer death would occur as a 
result of the accident Nonetheless, when a survey by area residents found a cluster 
of cancer deaths, there was concern in the community that accident releases had 
not been correctly estimated.

At the request of the Three Mile Island Public Health Fund, we agreed to investigate 
the situation further, by specifically testing whether the geographic patterns of 
cancer occurrence and airborne radiation emissions from the plant could be related. 
In addition to accident releases, we considered routine emissions from TMI during 
normal operation, since the plant operated for some years prior to the accident 
Outdoor background gamma radiation was considered as well, using data available 
from a national program that monitors background levels around nuclear facilities.
