摘要：
We reviewed the calibration procedures of gamma-ray spectrometry with particular emphasis to factors that affect accuracy, detection limits and background radiation in field measurements for dosimetric and radon potential mapping. Gamma-ray spectra were acquired in western Liguria (Italy). The energy windows investigated are centred on the photopeaks of Bi-214 (1.76 MeV), (TI)-T-208 (2.62 MeV) and K-40 (1.46 MeV). The inferred absorbed dose rate and the radon flux are estimated to be lower than 60 nGy h(-1) and 22 Bq m(-2) h(-1), respectively. (c) 2009 Elsevier Ltd. All rights reserved.
