Carborne gamma-ray spectrometry. Calibration and applications

Applied Radiation and Isotopes, 2006
Calibration of carborne gamma-ray spectrometry systems for (137)Cs is carried out with a source successively placed at 791 positions within an area of 34 m x 62 m. A computer model supplements the measurements. Hereby a sensitivity map for a surface contamination is generated as well as line and area sensitivities.
