An airborne radiometric survey can be an efficient way to investigate contamination of large areas after nuclear accidents. In the current study, a helicopter borne gamma ray spectrometry survey was carried out in a vast mountainous area in Norway, where the contamination from the 1986 Chernobyl accident still affects animal husbandry more than 30 years after the fallout occurred. The Cs activity densities provided by the aerial survey was validated using various independent ground-based measurements - including soil samples and in situ measurements (at 1 m above ground). Despite considerable small-scale heterogeneity, demonstrated by the ground-based measurements, strong correlations were obtained between the results from the aerial survey - after introducing more detailed instrument calibration and spectre analysis - and the ground-level data. Adjusted R values were around 0.9, and linear correlation coefficients close to unity.
