A complete survey was begun and readings of representative areas were recorded. Each day the same routine was followed and readings recorded to determine changes. Each day new "hot spots" were discovered that were not previously known to exist. Every effort was made to prevent anyone from receiving more than the established radiation tolerance. It was found necessary to caution men continually about precautions to be taken around radioactive areas. Some men were still Eound handling debris with bare hands, although rubber gloves were available. Men were worked in groups with one petty 4). officer for every five or six men (Reference
