To evaluate radiation risks and the exposure to human and marine life, samples of marine sediments were taken along Mediterranean Sea Coastline and Lake Burullus, Egypt. The current study sought to evaluate the levels of  226 Ra,  238 U,  232 Th and  40 K radioactive elements in surface sediments as well as their ecological concerns and potential sources using remote sensing and GIS. The multivariate statistical analyses were done to assume the inter-relationships between the radiological indexes and concentrations. The activity of radionuclides concentrations in sediments for  226 Ra,  238 U,  232 Th and  40 K were 13.81, 9.08, 15.28 and 155.48 Bq/kg, and 7.29, 5.84, 8.2 and 136.98 Bq/Kg for Lake Burullus and Sea, respectively. It is obvious that radionuclides concentrations are more in the lake than those of the sea, due to the nature of geological and tectonic structures of the lake. The activity concentration of  226 Ra didn’t exceed the world averages recorded by UNSCEAR but  40 K value exceeded this limit twice. The higher levels of  226 Ra were due to anthropogenic activities, Soil type and geological components which may influence the concentrations of the radionuclides. The multivariate analyses showed different trends to site 3 than other sites and different trend to  40 K than other radionuclides. Partial least squares regression (PLS) analysis indicated decrease in the elements in the area of Lake Burullus and increase in the coastline of Mediterranean Sea. With the exception of  40 k, all results indicated that radioactive pollution is safe and may not pose threat to human or the environment. Nevertheless, it is advised to apply cost–benefit analysis to maximize radiation protection.
