Abstract

The radon background correction is a crucial step in data processing of airborne gamma-ray spectrometry.In this article

we report the theory and mathematic model of spectral-ratio method to correct radon background in natural gamma-ray spectrometry.The relationship between survey height and calibration coefficients of terrestrial component spectra is analyze.The calibration coefficients can be obtained experimentally

and possible problems in spectral mathematical fitting can be avoided.
