Study of autoabsorption for total $\alpha$ and $\beta$ counting
M.A. Saettel1, A. Sellam1, A. Nourreddine1, A. Pape1

The RaMsEs Group (Radioprotection et Mesures Environnementales) of the IPHC performs research and offers services mainly in the field of radioactivity measurements and sample analysis. This report will describe some of our recent experience using a semiautomatic evaporation system to prepare large area thin deposits for total $\alpha$ and $\beta$ counting and gives experimental and simulated results for the autoabsorption coefficients.
