After the discovery of the neutron (1932) and of artificial radioactivity (1934), the neutron activation analysis (1936) will become the method of choice, (INAA: Instrumental Neutron Activation Analysis) is a exclusively method of elemental analysis. Its implementation involves irradiating the sample for analysis in a flux of suitable particles, neutrons, charged particles ... and identify, then after irradiation, radioactive isotopes created from the elements to be determined. The purpose of this study is calculated the concentrations of the elements of each element in the sample irradiated, using the absolute and comparative methods, this results are Compared with results certified standard of the International Atomic Energy Agency (IAEA) Soil-7, in the aim of validity the research, and repeat the need of some requirement in the different sectors such as the pollution of the air and water by heavy metals, food, medicine archaeology, geochemistry, biology, geology, agronomy and the hydrology.
