Estimation of the Point Radiation Source Activity Based on the Airborne Spectrometry
Jurečka, Tomáš ; Chromý, Adam (referee) ; Lázna, Tomáš (advisor)
The thesis deals with the localization of gamma-ray source and an estimation of its radiation activity with airborne spectrometry. In the theoretical parts are presented the types of ionizing radiation, the principles of measurement of gamma-ray by scintillation detectors and the explanation of airborne spectrometry. A revision of algorithms for data processing from aviation spectrometry was performed. In the practical part, the sensitivity of scintillation counter was determined depending on the height above the calibrated source. The mathematical methods for locating and estimating activity of the searched emitter were verified.
