On December 18, 1970, at 7:30 a.m., PST, a venting occurred at the Nevada Test Site in conjunction with the Baneberry test. The Lawrence Radiation Laboratory (LRL) Bio-Medical Research Division and the University of Utah responded to this event by activating their jointly operated air-sampling network and by gathering forage, milk, and animal samples. These data are used to calculate the dose to humans from inhalation, submersion, and food-chain contamination; food-chain contamination calculations are limited to the cow-milk pathway, but included bovine inhalation. The question of food-chain contamination is explored under both the actual situation that dairy cows were fed stored feed and under the hypothetical situation that dairy cows were fed fresh feed. Our results show that {sup 131}I was the significant radionuclide emitted by the event and that the strongest dose was received by the thyroid glands of both foraging animals and humans. The integrated concentrations of {sup 131}I were higher in the northern part of Utah; the maximum value of 1100 pCi h m{sup {minus}3} was recorded at Draper (near Salt Lake City). For conservative results, we calculated the dose to a child rather than an adult. For the actual conditions following the venting, we estimate on the basis of measurements of baled hay and or milk that the dose to an infant's thyroid via the cow-milk pathway was between 0.0065 and 0.012 rad at Draper. If cows had been continuously on fresh pasture, we estimate that the dose to the infant thyroid for the same integrated air concentration would have been 1.3 rad for dry deposition and up to 100 rad for wet deposition. 24 refs., 3 figs., 13 tabs.
