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 how chart for computer program have been discussed. This method provides a simpler
more accurate and reliable way to calibrate densimeter on the spot.
