Short summary
Airborne Gamma-Ray spectrometry (AGRS) is a rapid method to identify and quantify natural as well as man-made radionuclides in large areas. The quantitative response of a standard AGRS detection system was simulated with the Monte Carlo radiation transport code FLUKA. Based on validation measurements with radiation sources, the simulation results show superior accuracy compared to previous models. The validated model can be used for an improved calibration of AGRS systems.
