an empirical formula for the efficiency calibration of bulky source in cylindrical geometry is proposed.The simple but accurate empirical formula is able to effectively predict the efficiencies of summing effect free γ-rays from a cylindrical bulky source (Φ30 mm × 40 mm) at different source-to-detector distance.The relative difference between experimental and calculated data at 0

40
and 80 mm source-to-detector distances is smaller than 5%.
