Shielded recording gamma-radiation detectors of known geometry were located on two YAG’s to permit discrimination between the radiation fields resulting from water-borne and air-borne activities only. Unshielded detectors supplied data on the overall radiation fields on the weather decks. Recording radiation detectors inclosed in steel cylinders of various thicknesses supplied combined absorption and multiple scattering data as a function of time after detonation.; Major Descriptors: *FALLOUT -- DEPOSITION; *NUCLEAR EXPLOSIONS -- FALLOUT; *REDWING PROJECT; *SHIPS -- SURFACE CONTAMINATION Descriptors: EXTERNAL IRRADIATION; GAMMA RADIATION; PERSONNEL; RADIATION DOSES; RADIATION MONITORING; RADIATION PROTECTION; RADIOACTIVITY; SHIELDING MATERIALS; STEELS; TIME DEPENDENCE Broader Terms: ALLOYS; CONTAMINATION; DOSES; ELECTROMAGNETIC RADIATION; EXPLOSIONS; IONIZING RADIATIONS; IRON ALLOYS; IRON BASE ALLOYS; IRRADIATION; MATERIALS; MONITORING; RADIATIONS Subject Categories: 450200* -- Military Technology, Defense -- Nuclear Explosions & Explosives 10/5/769 00829665 (Item 469 from file: Weaponry, & National 103) ERA-07~-005350; EDB-82-004501 Author(s): Miller, G.C.; Schlei, E.J.; Andrews, C.R.

Country of Origin: United States Country of Publication: United States Abstract: The responses of a B-36 aircraft to the effects of a nuclear detonation at levels approaching the thermal and blast limitations of the aircraft were determined. A B-36D aircraft was instrumented and flown in the vicinity of each of the six shots of the CASTLE sequence. Time-history input and response measurements constituted the main instru mentation effort. For the first five shots, the aircraft was Major Descriptors: *AIRCRAFT -- BLAST EFFECTS; *AIRCRAFT -- TEMPERATURE EFFECTS; *CASTLE PROJECT; *NUCLEAR EXPLOSIONS -- SHOCK WAVES; *NUCLEAR EXPLOSIONS -- THERMAL RADIATION Descriptors: GAMMA RADIATION; VULNERABILITY Broader Terms: ELECTROMAGNETIC RADIATION; EXPLOSIONS; IONIZING RADIATIONS; NUCLEAR EXPLOSIONS; RADIATIONS Subject Categories: 450200* -- Military Technology, Defense --iNuclear Explosions & Explosives 10/5/770 (Item 470 from file: 103) 00828869 BRA-07-004885; EDB-82-003705 Author(s): Vine, F.S.; Owen, W.L.

On Shot 6, the aircraft was headed toward the ex plosion to obtain initial experimental data for this orientation. In addition to the measured data, together with photographs and descriptions of the damage, this report contains pertinent ob servations as reported by the flight crew.
