USE OF CONTROL CHARTS OF CUMULATIVE AMOUNTS FOR THE METHOD OF EXTENDING THE SERVICE LIFE OF THE IONIZING RADIATION SOURCE ACCORDING TO CALIBRATION RESULTS
The article forms and substantiates the application of control charts for the method of extending the service life of the source of ionizing radiation (SIR). An algorithm for its aim was developed. The main types of con- trol charts and the features of their application were considered. A methodology for constructing a cusum map for extending the service life of SIRs based on the results of their calibrations, as well as a methodology for checking the results of SIR calibration for statistical controllability, were developed.
