Caption for Figures The highest individual milk concentration (>30 pCi/1) of yi3l for each week reported in the U.S, Public Health Service Pasteurized’ Milk Network and the announced nuclear detonations. The hatched bars indicate the highest concentrations were outside the contiguous 48 states, Fig. Asterisk indicates joint US-UX underground test.
