The main purpose of this paper is to study a better calculating method for the source distribution of the multi-point source radioactive level. With the application of estimation and correction means and by creating a calculation model firstly, this paper concludes a computational formula which can realize the calculation of the multi-point source activity distribution according to the rod-like designing theory. After that, the non-linear output by theapproach of source activity compensation and residual errors analysis are corrected respectively, and the results are compared with the traditio...
