“…The improvement of AGRS data quality evolved side by side with the integration of geological data via increasingly refined statistical and geostatistical methods: the combined effect of both aspects allowed to go beyond traditional mineral exploration and lead to the investigation of new multidisciplinary fields, like landslide monitoring (Baroň et al, 2013), peat thickness 1 arXiv:1712.04777v1 [physics.app-ph] 13 Dec 2017 estimation (Keaney et al, 2013), prediction models for trees' growth (Mohamedou et al, 2014), radioelement distribution in weathered materials (Iza et al, 2016) and precision agriculture (Söderström et al, 2016).

Abstract. In this paper we present the results of a ∼5 hour airborne gamma-ray survey carried out over the Tyrrhenian sea in which the height range (77-3066) m has been investigated. Gamma-ray spectroscopy measurements have been performed by using the AGRS_16L detector, a module of four 4L NaI(Tl) crystals. The experimental setup was mounted on the Radgyro, a prototype aircraft designed for multisensorial acquisitions in the field of proximal remote sensing. By acquiring high-statistics spectra over the sea (i.e. in the absence of signals having geological origin) and by spanning a wide spectrum of altitudes it has been possible to split the measured count rate into a constant aircraft component and a cosmic component exponentially increasing with increasing height. The monitoring of the count rate having pure cosmic origin in the >3 MeV energy region allowed to infer the background count rates in the Tl photopeaks, which need to be subtracted in processing airborne gamma-ray data in order to estimate the potassium, uranium and thorium abundances in the ground. Moreover, a calibration procedure has been carried out by implementing the CARI-6P and EXPACS dosimetry tools, according to which the annual cosmic effective dose to human population has been linearly related to the measured cosmic count rates.
