Environmental monitoring is a control program that allows the assessment and prevention of potential environmental impacts that the INB activities may cause. Environmental monitoring programs are developed in each of the company's units from the ongoing review of environmental elements, such as water (rain, water channels and underground wells); soil, dust, agricultural products and other matrices.
Teams consisting of physicists, chemists and engineers compare these elements' analysis results with the figures found in the same sample collection points used before the beginning of the unit's operation, in order to detect possible variations in radiation levels or other contaminants.
This is also a way to ensure that the release of liquid and gaseous effluents of these units is under control, according to the standards established by CNEN and IBAMA.
In Caetité/BA, the Pre-Operational Environmental Monitoring Program established by the CNEN and IBAMA, held in 1989/1999, resulted in 10 years of records of radiation found naturally in the region. This information shows the characteristics of the soil, sediment, water, dust, and ambient radiation in the region before the start of the mine's activities and serve as parameters to compare with the analyzes that are regularly made through the Environmental Monitoring Program.
In Resende/RJ, the Pre-Operational Monitoring Program was carried out in 1980/1982, analyzing the environmental quality of the area within a 20 km radius from the Nuclear Fuel Plant. Sixteen matrices are permanently examined, among them, water, fish, sediment, air, soil and sanitary and industrial effluents.
Environmental monitoring is a requirement of the regulatory bodies CNEN and IBAMA, to which reports of the results are sent annually.
