Radiation Exposure Potential: High because of instrument placemen and recovery in contaminated waters. Staffing: Three civilians were associated with the project, all en SIO or University of California. No exposure is listed for one pe son; the others received 1.530 R and 0.035 R. Table 19. Exposures are givenjfin Exposures for the Sioux appear in Table 59. Project Report: Reference 47. Project 1.7 -- Ground-Motion Studies on Operations IVY and CASTLE Agency: Sandia Corporation (SC) Operations: Accelerometer stations were established at about eee (4.5-meter) depths on Eneman and Lele to record ground motion from KOON. Shots: KOON (Bikini). Radiation Exposure Potential: Staffing: Moderate. One person definitely associated with this project was 4 civilian from SC, but no exposure record is available for him. Project Report: Reference 48. Project 1.8 -- Dynamic Pressure Investigation Agencies: Ballistic Research Laboratories (BRL) 930lst Test Support Unit (Ordnance) Naval Administrative Unit (NAU) Operations: Jeeps and self~recording gauges were installed on oT kojlol, Enidrik, and Boken (for KOON), and Runit (for NECTAR) to da termine dynamic pressure as a damage parameter. Shots: KOON (Bikini); NECTAR (Enewetak). Radiation Exposure Potential: Moderate; resulting from data recovery and the inspection of the jeeps for damage and evidence of their m@vement. Six of the jeeps used in KOON were too contaminated to trang- port to Enewetak for use at NECTAR. 176
