Some larval fish and eggs were represented in the plankton catches, but these were not analyzed separately. Table 1 contains the results of the analyses of the three flying fish. The livers of the two fish caught north- west of Eniwetok had lower values (3200 and 6200 d/m/g) than that of the fish caught northeast of Eniwetok (22,000 d/m/g); the converse was true for muscle (680 and 1000 d/m/g vs. 210 a/m/e). Continuous Monitoring of Water: The values from the chart record are plotted in Figure 17, line A. A measure of contami- nation in the probe tank is indicated by the increase in the readings in Eniwetok lagoon at the beginning, midpoint and end of the survey, These values were 2 microroentgens on June ll, 9 on June 16 and 125 on June 21. A correction for the increase in background radiation was made. This was based on the assump- tlon that the contamination in the probe tank rose in a stepwise manner with an increase in background resulting from each encounter with radioactivity higher than the previous background level. The estimated background is shown in Figure 17, line B. The major increases in background were assumed to occur in the areas of stations le, 2c, 5c, 8a, 9c, and 7d. The background line, B, in Figure 17 was then used as the zero line in Figure 18. The differences between the background values and the observed chart values were plotted and the resulting line is assumed to be a more accurate representation of the radiation levels (Fig. 18). cays
