Abstract
The efficiency surface of the HPGe detector in close distance between the plane radiation source is studied in the paper. According to having been measured relative efficiency of 8 kinds of dot sources with single energy γ ray, the peak efficiency and the total efficiency surfaces of the HPGe detector are fitted. The true concidence correction factors of 60 Co and 152 Eu calculated by the efficiency surface agree with the experimental results measured.
