In this paper is introduced a method of using numerical analysis to solve calibration equations for nucleonic densimeters. Some problems such as equation simplification, choosing initial value of iterative function, convergency of iterative function and the flow chart for computer program have been discussed. This method provides a simpler, more accurate and reliable way to calibrate densimeter on the spot.
