Dlugosz-Lisiecka and Bem (2013) have analyzed the dependence of the self-absorption correction factor for the 210Pb activity on the activity ratios of 911 and 209 keV peaks and 609 and 295 keV peaks coming from nuclides of 238U or 232Th rows, present in typical environmental sample.
Has anyone used this method? How do I do the correction step by step?
Read the follow paper:
Cutshall NH, Larsen IL, Olsen CR. Direct Analysis of Pb-210 in Sediment Samples - Self-Absorption Corrections. Nuclear
Instruments & Methods in Physics Research 1983; 206: 309-312.
Have a nice day.

Hi Zhou
You can also look at this paper:
1. Hurtado S., Villa M., Manjon G., G. R. A self-sufficient and general method for self-absoprtion correction in gamma-ray spectrometry using GEANT4. Nucl. Instruments Methods Phys. Res. 8–11 (2007). doi:10.1016/j.nima.2007.05.090
I am sending you a chapter of a book, where self-absorption issue is discussed.
You can also read the following paper containing theoretical, experimental and Monte Carlo methods to assess the self attenuation correction for Pb-210:
Saïdou., Bochud, F., Laedermann, J.-P., Buchillier, T., Kwato Njock, M., Froidevaux, P. Calibration of an HPGe detector and self attenuation correction for 210Pb: verification by alpha spectrometry of 210Po in environmental samples, Nuclear Instruments and Methods in Physics Research A 578 (2007), 515-522.
Good day. Please go through this paper.
