Stirling, H J; Nelson, C H; Brizius,

The objectives of these tests were to determine (1) the blast and shock effects for two overpressure areas on explosion-proof television pan-and-tilt mechanisms, the cameras contained therein, and special shutter mechanisms; (2) the effects of varying amounts of radiation on the radiation-sensitive components of a special shutter mechanism and circuitry of a television camera; and (3) the effectiveness of a special shutter mechanism designed to protect the vidicon tube of a television camera against excessive light damage and to make a motion picture record of the shot as viewed on a television monitor. It was found that the semiconductors used in the electronic circuitry were affected to some degree by nuclear radiation. In general, the transistors showed significant reductions in current gain and the diodes showed increased forward drop; the zener diodes which were also exposed were affected very little by the nuclear radiation.
