USFS. U.S. Forest Service. USNS. United States Navy Ship; vessels of this designation are manned by civilian crews. JSTEF, VC. Underwater Sound Transmission Experimental Facilities. Fleet composite squadron (formerly VU). Yersene. A detergent. Viking, NVP-29. Radio call sign of VIP aircraft. Kwajalein-based naval patrol squadron that flew security sweeps in P2V-6 aircraft during CASTLE. VR-7. Naval air transport squadron. Vd-1. Airborne early warning squadron. aAQC. Wright Air Development Center, Wright-Patterson AFB, Ohio (Air Force). Used for aerial monitoring of radiation during CASTLE. 43-29, Weather reconnaissance version of 8-29 used for cloud tracking and sampling. aB-35, Weather reconnaissance version of 8-36. weapon debris. The radicactive residue of a nuclear device after it has been detonated, consisting of fission products. various products of neutron capture, weapon casing and other components, and uranium or plutonium that has escaped fission. anole body irradiation. Exposure of the body to ionizing radiation from external radtation sources. Critical organs for the whole body are the leans of the eye, the gonads, and the red-blood-forming marrow, As Jittie as only 1 cm? of bone marrow constitutes a whole-hady exposure. Thus, the entire body need not be exposed to be classed as a whole-body exposure. di‘son. Radio call sign for WB-29 cloud tracker aircraft. Wilson cloud. A mist or fog of minute water droplets that temporarily surrounds a fireball following a nuclear detonation in a humid atmosphere. This is caused by a sudden lowering of the pressure (and temperature) after the passing of the shock wave and quickly dissipates as temperatures and pressures return to normal. ' worldwide fallout. Consists of the smaller radioactive nuclear detonation particles that ascend into the upper troposphere and the stratosphere and are carried by winds to all parts of the Earth. The delayed (or worldwide} fallout is brought to Earth, mainly by rain and snow, over extended periods ranging from months to years. WREP. WI. Weather Reporting Element Provisional. Prefix of Weapon Test (WT) report identification numbers. results of scientific experiments. YAG. YC. These reports were prepared to record the Miscellaneaus auxiliary ship (Navy). Open lighter (nonself-propelled; Navy). YEN. Covered lighter (nonself-propelled; Navy). yield. The total effective energy released in a nuclear detonation. It is usually expressed in terms of the equivalent tonnage of TNT required to produce the same energy release in an explosion. The total energy yield is manifested as nuclear radiation (including residual radiation}, thermal radiation, and blast and shock energy, the actual distribution depending upon the medium in which the explosion occurs and also upon the type of weapon. See TNT equivalent. yield (blast). That portion of the total energy of a nuclear detonation that is identified as the blast or shock wave. field (fission). That portion of the total explosive yield attributable to nuclear fission, as opposed to fusion. The interest in fission yield stems from the interest in fission product formation and its relationship to radioactive fallout. YO. Fuel 911 barge; self-oronel led, 485
