Project 4.2 was designed to study the direct (primary) air blast injury, in animals, from an atomic weapon in the range of 20 to 50 psi under circumstances affording protections against missiles, thermal, and ionizing radiation and to estimate the probably direct air blast hazard in man. Two animal species of widely different body weights (700 rats and 56 dogs) were exposed, together with air pressure recorders, in aluminum cylinders, covered by sandbags and dire but open t both ends, at seven stations distributed within the intended overpressure range of 20 to 50 psi of Shot. About 200 rats were likewise exposed in Shot 9. Most of the animals were dead upon recovery. The rats recovered from Shot 9 were exposed to a recorded pressure of 18 to 24 psi. The autopsy findings were typical of those seen following exposure to air blast from HE or in the shock tube. Laboratory studies were planned to evaluate the relative importance of the several blast wave parameters in the production of injury. R. H. Draeger was at one time the NMRI's head of atomic-radiation-and-detection. Operation Upshot–Knothole was a series of eleven nuclear test shots conducted in 1953 at the Nevada Test Site. It followed Operation Ivy and preceded Operation Castle. The test series was notable as containing the first time an AFAP shell was fired (GRABLE Shot), the first two shots by University of California Radiation Laboratory—Livermore (now Lawrence Livermore National Laboratory), and for testing out some of the thermonuclear components that would be used for the massive thermonuclear series of Operation Castle. Condition: Good.
