|
 | The primary objective of this project was to determine the military significance of fallout contamination from small yield fission weapons. The specific objectives were to (1) make the necessary measurements during Shot Fig to delineate the fallout gamma-radiation field produced by a land-surface detonation of a fission weapon; (2) use data collected to construct a fallout model for use with any wind pattern, and evaluate extremes in militarily significant contamination ... |

| The Assessment of System and Component Reliabilities Based on Both System and Component Test Results. |

|
 | Two problems are considered in the report; the determination of confidence limits for system reliability based on component results with and without the inclusion of system results, and the determination of confidence limits for component reliability based on component and system results. The method of maximum likelihood is used to obtain estimates of the first two moments of the maximum likelihood estimate of reliability. These estimates are then equated to ... |

| EVALUATION OF VHF OF LORAN-C DATA. |

D. W. Miko; SANDIA CORP ALBUQUERQUE NM
|
| The report describes and summarizes the results of an experiment in which Loran signals are relayed through a VHF data link to a conventional Loran receiver. Loran signals are received at a field transponder, amplified and inputed to a VHF FM transmitter as modulation, transmitted to a remote location where the VHF signal is demodulated and inputed to a Loran-C receiver as a normally received pulse train.

| Project Sedan, Nevada Test Site, July 6, 1962. Close-In Air Blast From a Nuclear Event in NTS Desert Alluvium |

|
| Close-in air blast from the Sedan event was considerably greater than expected on the basis of previous measurements of blast from nuclear events in basalt and from HE events in both basalt and alluvium. In Spite of overranging of the pressure gages, the measurements permit derivation of a lower limit of peak overpressure and an upper limit on the amount of blast Suppression resulting from charge burial. Comparison of Sedan ... |

| Blast Measurements On A Medium-Yield Surface Burst |

|
| Overpressure and dynamic pressure were measured as a function of time and distance (690 to 3,250 feet) on a surface burst of a medium yield (40 kt) nuclear device on Site Yvonne, Eniwetok. Overpressures were measured with ground baffles and pitot-static gages. A precursor formed but died out at an unusually high overpressure of between 35 and 55 psi. The usual high dynamic pressures associated with precursors were observed. Outside ... |

| LONG-DISTANCE BLAST PREDICTIONS, MICROBAROMETRIC MEASUREMENTS, AND UPPER-ATMOSPHERE METEOROLOGICAL OBSERVATIONS FOR OPERATIONS UPSHOT-KNOTHOLE, CASTLE, AND TEAPOT |

|
| A blast prediction and microbarograph observation program was operated by Sandia Corporation during Operations Upshot-Knothole, Castle, and Teapot. Refined methods for blast prediction were derived which appear to predetermine adequately the possibility of blast damages occurring out side the Nevada Test Site during test operations. In addition, sound recordings have been used for inverted geophysical seismic exploration of winds and temperatures in the ozonosphere, 30-60 km above the earth. (Author) ... |

|
| Operationally, Sandia Laboratory's instrumentation program consisted of shelter installations, gauge installation, and the associated liaison and logistics. These projects were concerned with blast air pressures, temperatures, winds, and underwater pressures. The area covered by the measurements extended along the Eniwetok Atoll from Gene to Elmer for which seven shelter installations were made. All shelters were used on Mike shot, and two were used on King shot. A total of 125 ... |

|
| The Tumbler series of airbursts was designed primarily to obtain pressure measurements useful in constructing an experimental, rather than solely theoretical or extrapolated, height-of-burst chart for atomic weapons. Also, peak pressures observed on Operation Buster were much lower than had been anticipated, and their verification by further tests was indicated. Specifically the Tumbler series was planned: (1) to provide pressure data from the burst of a 1.2-kt weapon at a ... |

| SOME MEASUREMENTS OF TERRAIN EFFECTS ON BLAST WAVES |

M. L. Merritt; SANDIA CORP ALBUQUERQUE NM
|
| During Operation Buster some of the nearby hills were instrumented using pressure gauges in an attempt to explore the manner in which terrain features influence the propagation of blast waves. Because of loss of records from experimental difficulties and lack of duplication of gauges, results are, at best, fragmentary. The evidence on the protective effects of hills is inconclusive, but there is definite evidence of a change in a blast ... |
