A study was conducted in central New Mexico to evaluate the levels and distribution of plutonium resulting from the detonation of the Trinity device in 1945. A total of 88 soil samples were collected, covering an area of roughly 4500 square miles. Air samples were collected during 1975 at a location within the Trinity fallout pattern, and at another site outside the pattern. All samples were analyzed for plutonium-239,240 by alpha spectroscopy, and some were analyzed by mass spectroscopy for both nuclides. Trinity plutonium can be distinguished from global fallout plutonium by the ratio of the two plutonium nuclides. The results indicate that most of the area sampled contains detectable amounts of Trinity plutonium in the surface 5 cm of soil. The highest levels of plutonium-239,240 deposition in soil (in unrestricted areas) were on the order of 90 nCi/m2. The air samples at the site within the fallout pattern contained about 50 percent Trinity plutonium, but the average concentration of airborne plutonium at the two locations was the same.
