Data are presented from the radioanalysis of tissues collected from cattle and mule deer, desert bighorn sheep, feral horses, and other wildlife that resided on or near the Nevada Test Site during 1976. Other than the naturally occurring potassium-40, gamma-emitting radionuclides were detected infrequently with the exception of exp 131 I in animal thyroid samples collected after September 25 (the date of a Chinese nuclear test). Strontium-90 concentrations in bones from deer, cattle, and desert bighorn sheep continued the downward trend of recent years. Tritium concentrations were generally within ambient limits with the exception of animals exposed to sources of contamination; e.g., Sedan Crater, drainage ponds from Area 12 tunnels, etc. Analysis of actinide in tissues was emphasized during 1976. Graphs illustrate the exp 239 P levels in lungs, livers, and femurs from Nevada Test Site beef cattle for the years 1971 through 1976. Femur and lung residue data are nearly identical for each year with liver concentrations being a factor of 2 or 3 lower. Hypothetical dose estimates to man were calculated on the basis of the daily consumption of 0.5 kilogram of liver or muscle from animals that contained peak actinide levels. The highest postulated dose was 11 millirem from tritium from tissues for a mule deer. This dose is about 2% of the 500 millirems/year guide for radiation doses to an individual in the general public. All other postulated doses for consumption of the tissue containing other radionuclides are less than 0.1% of this guide. The food habits of desert bighorn sheep were discussed according to the geographic locations of the animals at time of collection. Grasses made up approximately 60% of the diet at all locations, with shrubs content approaching 30%, and the remainder consisting of various forbs. The movement of 13 mule deer fitted with collars containing a radiotransmitter unit was monitored on a weekly basis. (ERA citation 04:020350)
