John N. wolfe April Ly, Lag2 ft) Dr. cases, beginning with the very earliest years of the Laboratory's experience, the “crash" programs subsequently became regularlysupported aspects of the total activity. This was true, generally, of the Laboratory's continuing involvement in the nuclear test programs in the Pacific. It was true, specifically, of tha Laboratory's work at Rongelap, where an emergency monitoring incident eventually became a long-term bioenvironmental study of interest to the Commission. These developmenta are attrib- utable to the fact the Laboratory never considered itself merely engaged in monitering, but rather attempted in every possibie instance to meet the immediate needs of the Commission and at the same time to extract from the immediate situation all available information of a basic nature. The periods and programs in which the Laboratory has been asked, over the years, to provide special services may be summarized as follows: 1946 o gadg: The Laboratory, which for three years had been developing studies of the effects of X~radiation on aquatic biota, was drawn into the Pacific during the first of the nuclear test programs. This occurred at the time the ARC was being created by the Atomic Energy Act of 19345, but this Pacific experience set the pattern for later environmental studies at remote field sites. 1947 BikiniResgurvey: The staff was called from labor- atory studies to participate in Navy-supported evaluation of Bikini Atoll. 1948 tone: Eniwetok Atoll, the 1946 Sandstone test series, was subjected to post-test evaluations. The Laboratory made a new survey of Bikini, 1949 the site of Bj ~E eto s New examinations of the test atolls were made at the request of the Commission. Program emphasis now was shifted almost entirely to the Pacific, virtually ceased. and residual work in X-radiation
