Calibration of the Concorde Radiation Detection Instrument and Measurements at SST Altitude,
Abstract
Performance tests were carried out on a solar cosmic radiation detection instrument developed for the Concorde SST. The instrument calibration curve (log dose-rate vs instrument reading) was reasonably linear from 0.004 to 1 rem/hr for both gamma radiation and fast neutrons. Nonlinearity in the calibration curve was observed at dose rates below 0.003 rem/hr. The instrument responded normally after exposure to 30 rem/hr of gamma radiation. The charged particle detectors showed a directional response apparently because of the neutron moderator. The neutron detector did not show a directional response. Measurements made with the Concorde instrument at 60,000 ft. and high geomagnetic latitudes indicated a galactic cosmic radiation dose rate of 0.7 - 0.9 millirem/hr. (Author)
