RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL MOIEREM eo eee N ITEM GZ EASY AND X-RAY GZ MAIN ROAD so Ew BASELINE FIGURE 7-8. ENJEBI PLOW X SITES. On 13 June 1978, Dr. Chester Francis, of the Oak Ridge National Laboratory (and a memberof the Bair Committee), and Dr. Rollin Jones, of the University of Hawaii, arrived at Enewetak to conduct the experiment.® The area identified as X-1 was selected and became known t | simply as the Plow-X area. Extensive radiological measurements were made to characterize the distribution of radionuclides. Each 25-by-25meter area was measured with the in situ van while soil profiles were collected down to 50 centimeters at four locations and to ground wateror bedrock at one other (Figure 7-9). IMP results showed the area to be contaminated from 49 to 109 pCi/g transuranics over the plot with an average of 71.5 pCi/g. Surface soil samples gave a range of 42 to 208 pCi/g
