The irtroduction of tungsten during the U. S. "Hariltack" nuclear test series provided a unique opportunity for identifying nuclear debris of known origin. From June l958 to August l959, 74-day W/sup 185/ was detected in precipitations. The deposition of W/sup 185/ and Sr/sup 90/ in precipitation at Westwood, N. J., is shown graphically, together with the amount of rainfall. All of the tungsten results were corrected for decay to August 15, l958. A similar graph is given showing the variations of specific activity of Sr/sup 90/ and W/ sup 185/ in rainfall from June l958to July 1959. The W/sup 185/ to Sr/sup 90/ ratio is plotted as a function of time over the same period. The W/sup 90/ data demonstrated that material injected irto the stratosphere in the equatorial regions is involved in the seasonal variations of fall-out. (B.O.G.)
