1090th USAF Special Reporting Group 1083rd USAF Special Reporting Squadron Operations: A total of 71 self-recording instrument statiomgs were installed at islands and reefs of both atolls. Shots: All. Radiation Exposure Potential: Moderate (gauge installationfand pickup). Staffing: Nineteen men were associated with this project, five from BRL; two from the 1090th, one from the 1083rd, and eleven fJom the 930lst (six Air Force and five Army). the rest, military. Project Report: Those from BRL were fivilians, The group's exposures are presented in| Table 19. Reference 44. Project 1.3 -- Dynamic Pressure Measurements Agency: Sandia Corporation (SC) Operations: Instrumentation was installed at various statipns to measure the theoretical relationship between dynamic pressufe and overpressure to evaluate gauges. Shots: All. Radiation Exposure Potential: Moderate (data recovery and Bauge placement in contaminated areas). Staffing: Two civilians from SC received totals of 1.315 and 1.195 R; however, this should not be uniquely associated wikh this project as the same two men are also cited in the project Project 1.2a.
