These were mostly steel cables and pieces of steel reinforcing rods in concrete fragments. key ee cower Sper ey E. Enidrik Enidrik is the largest island of the scuthern group and is fourth largest of the atoll. It is less than one mile west of Eneman. The vegetation is quite thick, particularly in the island interior. There are stands of cordia and pisonia trees and several pandanas trees with the usual ground cover of scaevola, messerschmidia, and guettarda. Several survey transects were made from lagcon to ocean side on the eastern part of the island. Survey of the larger western part was less systematic due to the density of vegetation. bea meni, Readings with the G-M counter on the eastern part of the island generally ranged from 3 to 10 ur/hr. In one area near the eastern end, a reading of 30 ur/hr was obtained. Some metal scrap in this region exhibited significant contamination. The western part of the island showed variaticns in the radiation levels similar to Bikini - low levels near the ocean and lagoon shore with higher levels inland, indicative of greater retention of radioactive products by the organic soil. Measurements with the scintillation counter ranged from 3 to 19 ur/hr on a transect near the center of Enidrik. The range was 9 to 235 ur/hr on a transect farther to the west. The low level was near the ocean high tide line. Mid-island on this transect the levels were around 30 to 90 Bee at, ee nn OE Maye
