摘要: Abstract A method of γ-ray efficiency determination for extended (plane or bulk) samples based on numerical integration point source is studied. The proposed widely applicable to various shapes and materials. geometrical factor in the peak can easily be corrected by simply changing region, self-absorption also absorption coefficient sample matrix.
