“…These results indicate that the abnor tional 101 samples of rain and snow collected mally high Pu/U ratios reported for the volcanic at Fayetteville during the period from January samples are most likely due to radioactive 1981 through April 1983. The plutonium data fallout contamination (Fried et al, 1985;Sandoval et al, 1985;Essien and Kuroda, 1985). This means that the surface of the entire earth is contaminated with `man-made' plutonium and, whenever a major volcanic eruption occurs, a large quantity of plutonium together with uranium is blown up into the troposphere and the stratosphere resulting in a world-wide fallout of plutonium.…”
