Considerable data has been compiled to show that the global fallout ratio of 137g of data to 906, shows averages the 1.45. A lesser, 239+ 2405, fallout to but 90g, ratio ratios were confirmed in open-ocean air samples collected 1977; in 0.01340.003 late was 0.015, which 13706 to measured can be 90.5, predicted of on 13765 Estimated concentrations and of the to 905, in concentrations This in 13765 with rain 5 compared the 6 of average fallout from respective Table of ratio computed the in the Expected are and These ratio relating fallout. in Table are ratios 0.022.
