Photon attenuation for samples in Marinelli beaker geometry: an analytical computation.
A simple but precise mathematical method is used to estimate self-attenuation corrections for Marinelli beaker samples; the method may be useful for environmental monitoring and complements experimental calibration data. Self-attenuation corrections for a given sample depend not only on the sample geometry and linear attenuation coefficient, but also on detector parameters and photon energy. In the present analytical computation, the dependence on detector parameters and photon energy is neglected. The resulting errors are smaller than 5%.
