Using Mathematical Procedure to Compute the Attenuation Coeffi cient in Spectrometry Field

In gamma-ray spectrometry, the analysis of the environmental radioactivity samples (soil, sediment and ash of a living organism) needs to know the linear attenuation coefficient of the sample matrix. This coefficient is required to calculate the self-absorption correction factor through the sa...
