Atomic radiations are found in layers of the earth containing crude oil of terrestrial origin and formed under the influence of pressure and temperature in the ground, and when extracting crude oil, its exit is accompanied by water with high levels of salts, and these salts are calcium carbonate, calcium sulfate, and barium sulfate. According to the laboratory analyzes conducted in the chemical and physical analysis laboratory. It showed that the presence of these salts in the field well water is considered to have a high absorption property because it absorbs some radioactive isotopes from the ground, and these isotopes are Thorium and Uranium. And through field operations of radioactive materials and measurement of contamination rates in crude oil for different locations in the field to know the extent of damage to humans and the surrounding environment, methods of dealing with it and how to prevent it. Two types of measuring devices have been used, the first is a device for measuring (Gamma) radiation, and the second is for measuring radioactive contamination (Alpha and Beta). Where the radioactive sampling sites were chosen in order to measure the level of radioactive contamination in them, and these sites are the complexes in which crude oil accumulates after leaving the wells to the field and then to the oil ports, and these complexes located in The Sarir Field are (GC-1, GC-2, GC-3, GC-4), where the results showed that all the field readings that were taken are very dangerous readings compared to the permissible limits for radioactive materials according to the Atomic Energy Agency regulations guide.
