Oe in the vicinity of Nam (Charlie) Islet. The larger species were found near Bikini Island. In response to a special request to check the levels of radioactivity at Aerokoj Islet, received during the survey, the land hermit crab, a known concentrator of 90Sr, was collected. Since coconut crabs are both an indicator organism and a food item, they would have been sampled instead of hermit crabs, but coconut crabs were not found on Aerokoj.

Although the curlews and turnstones are transients and are present in small numbers, at most a few hundred, they contain the highest levels of radionuclides among the birds. turnstones, noddy terns, Curlews, and fairy terns were sampled. 8LE1O0S Rats are not used as food but they are the only mammal living on the atoll, and a few were taken to determine their radionuclide content. of Energy Department fice Historian’s Of ARCHIVES “ Groundwater was collected by driving half-inch pipe with well points into the soil.
