Alpha-spectrometric thin source preparation with emphasis on homogeneity

Differently shaped Pt anodes were used in the electrodeposition procedure and their influence on the quality of the thin layer of deposited radioisotopes was studied. In the micro-coprecipitation procedure the influence of working under vacuum on the homogeneity of the sources was investigated. The homogeneity of the alpha sources was checked by visualization of the activity distribution of the sources using autoradiography.
