摘要
Developments are described in the preparation of 4πβ sources. A method for synthesizing conductive polyaniline (PANI) and preparing a thin film made of PANI is proposed. The films obtained by this method are electrically conductive, homogeneous, and chemically and mechanically stable. Quantitative 4πβ sources required for activity measurements have been made by using the above films as a source support. The results show that this new source-making method can satisfactorily meet the needs for 4πβ—γ coincidence.
