APPENDIX B TABULATED DATA B.1 TOTAL-COLLECTOR AND RAIN-GAGE DATA Tables B.1, B.2, and B.3 list the amount and activity of fall-out collected in the total collectors and the rain-gage buckets. Values of activity have been corrected to a commondate of 21 November 1952, and both weight of fall-out and activity are expressed in units per square foot. To obtain the total weight of solids that arrived at each station, the leached activity in the rain water was converted to an equivalent weight of solid, and this value was addedto the weight of solid collected. This conversion was accomplished by assuming that the quantity of material leached was proportional to the amountof activity leached. B.2 SECONDARY FALL-OUT DATA Data listed in Table B.4 represent the activity collected on the gummed-papercollectors located at the weather islands and aboard the task force ships. Each collector consisted of 2 sq ft of Kum-Kleen gummed paper, and exposures were made for either 12- or 24-hr periods. All counting data are corrected to 21 November 1952. B.3 SUMMARY OF DATA COLLECTED ON THE FREE-FLOATING SEA STATIONS The free-floating sea stations were not in the area of primary fall-out, and those data collected represent the activity from secondary fall-out only. Recovery of the sea stations was made while the secondaryfall-out was arriving, so the data are of little value. Each station was equipped with a total collector as well as 1 sq ft of Kum-Kleen gummed paper All counting data were corrected to 21 November 1952 and are listed in Table B.5. 59
