PREFACE

This report was prepared by technical staff members of the Nuclear Regulatory 
Commission (NRC), the Department of Health, Education and Welfare (HEW) and 
the Environmental Protection Agency (EPA), who constitute an Ad Hoc Population 
Dose Assessment Group. It is an assessment of the health impact on the 
approximately 2 million offsite residents within 50 miles of the Three Mile Island 
Nuclear Station from the dose received by the entire population (collective dose). 
The Ad Hoc Group has examined in detail the available data for the period up to 
and including April 7, 1979. Based on a preliminary review of data from periods 
beyond April 7, it appears that the collective dose will not be significantly 
increased by extending the period past April 7.

The dose and health effects estimates are based primarily on thermo-luminescent 
dosimeters placed at specific onsite and offsite locations. The dosimeters measure 
the cumulative radiation exposure that occurred at these locations. They permit the 
most direct evaluation of dose to the offsite population from radionuclides 
(radioactive materials) released to the environment.

The report also addresses several areas of concern about the types of radionuclides 
released, about the contribution to population exposure due to beta radiation (which 
does not penetrate the clothing and skin) emitted from the released radionuclides, 
about the degree of coverage afforded by available radiation measurements, and 
about the range of health effects that may result from the estimated collective dose.
