ISOPLETHS OF FINAL ESTIMATED SURFACE TRU ACTIVITY IN pCi/g FOR ISLAND URSULA 7.4.13 Vera Background Island Vera (Marshallese: Alembel) is a moderately-sized island in the east-northeastern part of the Atoll, having an area of 15.5 hectares. The island was densely vegetated and had several mature eoconut palms, Few pieces of debris remained from the test operations thus no significant soil disturbances occurred due to debris removal. No ground zero sites were located on Vera and it ranks 22nd of all islands in the Atoll in total H + 1 hour exposure rate with 270 R/h. There were no known or suspected burials of radioactive materials on this island. 1972 Survey During the 1972 survey, soil samples were collected at 25 sites on Vera and a few vegetation samples were also taken. Three of the 25 locations were 0-35 em profile samples and the remaining 22 locations were 0-15 cm core samples, The results from the prof ile samples indicated a steady decrease in activity with increasing depth for 137g, 90Sr ang 239,240py data. Tables 7-1, 7-2 and 7-3 give 0-15 em summary results for I3ieg, 40sr and 239,240 py respectively, for the data collected in 1972. 255
