Abstract: The high resolution of radioactive measurements acquired by the spectrometric gamma-ray technique were applied in the research area and subjected to statistical analysis, in order to draw valid conclusion, regarding the nature and significance of the distribution of the radioelements, that it represents each input element individually. The qualitative interpretation showed seven anomalous parts in Roseita branch and four anomalous parts in Damietta branch. The quantitative interpretation used traditional statistical treatment the calculated arithmetic mean, standard deviation, range difference (between the minimum and maximum values), standard error, Coefficient of Variation (CV%) and 95% Confidence Interval for the Mean (lower bound and upper bound). Meanwhile, the advanced statistical treatment, such as test of homogeneity Levene’s Statistic, ANOVA test, K mean clustering and post Hoc of the multi comparison among the separated eleven groups. As well as they help to define their original source behaviors.
