A comparison of the concentrations of tungsten-185 and strontium-90 in the air at various times after the 1958 U.S. nuclear tests in the Pacific indicatesthat debris from this test series contributed less than 10 percent of the total Sr90 content of the ground-level air at Miami and Washington during the spring of 1959.
