In this work we use the laws of statistics and statistical distributions software to try to understand the random statistical nature of the dissolution of gamma rays and their interaction with the material by studying the spectrum regions of the sodium-22 spectrum using the statistical programming language R. such Normality test, Anova Test as well as Pearson correlation coefficient test and the linear Regression test and we were found that there is no strong statistical relationship between the random variables studied using linear regression, also it was found that the average mean of the standard samples follows the normal distribution and this was confirmed by using the T-test, there is also a slight difference between the sampling random mean and the standard mean for the same samples using the same statistical distribution.
