Exposure of the general population near TMI (Three Mile Island)

During the Three Mile Island Unit 2 (TMI-2) accident, radioactive steam and water from the primary cooling system entered the auxiliary building and quantities of the volatile fission products, mainly the noble gases, entered the building atmosphere and were discharged to the environment by the ventilation system. In the days following the accident, the largest concentration of skilled radiation monitors in history assembled at Three Mile Island. Tens of thousands of measurements of many kinds were made and the data gathered by specialists from the staffs of the Kemeny Commission, the Commonwealth of Pennsylvania, the US Department of Energy, its national laboratories, the US Nuclear Regulatory Commission, the Environmental Protection Agency, and the US Department of Health Education and Welfare. By the time the Kemeny Commission report was published in late 1979, the most probable collective dose was estimated to be 2000 prem, which is toward the lower end of the range of estimates reported by the interagency committee. This is equivalent to the dose received by 2 million people in /approx/3 days from natural sources of exposure. The maximum dose to any individual in the off-site general population was by then reported to be /approx/70 mrem, or somewhat less than the dose received from nature in 1 yr.
