Abstract
At the flight altitudes of modern airplanes, cosmic rays intensity is several times higher than on the Earth's surface. The radiation field is not constant in time and due to various effects, not routinely considered in calculations, the exposure can increase several times. Therefore, a continuous monitoring of radiation exposure on board is required. This article characterises newly developed detectors Airdos-C with diverse scintillation crystals. Unlike detectors based on a Si diode, which are commonly used for long-term measurements, these detectors can also be used for detection of high-energy gamma-rays generated in thunderstorms. For a correct interpretation of the measured data it is important to perform an energy calibration and to verify the detector response in known radiation fields. The results obtained with several radionuclide sources were analysed using mathematical statistics methods. The detectors were also exposed onboard aircraft under well-defined conditions.
