[en] This report contains a preliminary assessment of the radiation dose and potential health impact of the accident on March 28, 1979 at the Three Mile Island Nuclear Station. This assessment was prepared by a task group composed of technical staff members from The Environmental Protection Agency, The Department of Health, Education and Welfare, and The Nuclear Regulatory Commission. The estimated dose that might have been received by an individual is less than 100 mrem. The collective dose received by the 2,164,000 people estimated to live within 50 miles of the reactor site is calculated to be 3,300 person-rem (with a range of 1600 to 5300 person-rem). This corresponds to an average dose of approximately 1.5 mrem. The potential number of fatal cancers that is projected to occur as a result of the accident is less than 1. This potential impact would be undetectable compared to the 325,000 cancer deaths that would normally be expected to occur in a population of 2,164,000. The estimated total health impact, including fatal and non-fatal cancers and genetic effects to all future generations is approximately 2 health effects

[en] Analysis of the activity level of C-14 contributed from the nuclear fuel cycle and non-fuel sources to LLW sites in the period from 1985-2004 provides the following information: 2100 Ci from the nuclear fuel cycle; 1650 Ci from institutional wastes; 2150 Ci from industrial wastes. The chemical form of the C-14 in the fuel cycle waste approximates 75% inorganic (carbonate), 20% activation metal, and 5% organic radiocarbons. The chemical form of the institutional and industrial carbon-14 waste is believed to be essentially 100% organic radiocarbon compounds. The transport of C-14 from the low-level radioactive waste site is believed to be largely as a gaseous release to the atmosphere

[en] The Three Mile Island Accident is described. The pathway and quantity of radioactive materials released, the radiological monitoring results and health effects are discussed. It was concluded that while radiological releases were small in view of the magnitude of fuel damage, the accident indicated that better health physics instrumentation and personnel training is required.

[en] The radiological consequences of the Three Mile Island (TMI) nuclear accident are discussed in detail. The nature, quantity and timing of the radioactive materials released to the atmosphere are established; mainly radioactive noble gases were emitted. A description is given of the radiological monitoring that occurred and the measured levels both inside and outside the plant are given as a function of time from the accident. In particular, the radioiodine release and its subsequent detection in milk analysis is described. The methods of establishing the population dosage are discussed; it is concluded that the collective dose equivalent is in the range 1600-3300 person rems. This implies a projected cancer (fatal and non-fatal) incidence of less than 1.5 in the offsite population within the 50 miles of the TMI site; the expected occurrence in this population is 541,000 cancers. The exposure of workers to radiation levels within the plant is also reported. (U.K.)
