92 1966-67 NEW FILMS wetok atolls six years after the last nuclear test detona- tions, and how it is found that there has been tremendous recovery to the biological processes that form the life chain linking man with the tiniest plants, fish and animals in the atolls. Under an AEC contract, scientists of the University have been studying the biological after-effects of nuclear tests at the mid-Pacific atolls intermittently since 1946. Returning in August 1964, the team of biologists sets out to determine how much radiation remains, what changes have occurred on the reefs, what has happened to birds, land animals and to fish in the lagoons, and what kinds of plants have come back. The scientists find that: the islands are once again lush with vegetation, external radiation levels have dropped to levels safe for people and the radioactive burdens in animals and plants are low, rainwater in the soil is safe for drinking, coconut trees are increasing again, all the expected species of fish and sealife are to be found, birds are thriving, and that the sea—surging through the coral reefs—has cleaned, restored and nourished the atolls. The scientists conclude that the gross results of nuclear testing are fading, and what little biological damage re- mains is rapidly healing.
