RESUMO:

Brazil has one of the largest uranium reserves in the world. Usually this metal is available inside the earth's crust, however, natural and anthropic processes contribute to its redistribution throughout the environment. By treating a radioactive metal, uranium has a structure in which the soil is disintegrated into other products such as radiation and elements of varied toxicity such as radiant gas and lead. In the Brazilian semi-arid, specifically in the municipality of Lajes Pintadas / RN, there are rocky outcrops with a presence of natural ionizers that release the radiant gas and, consequently, lead to the environment. The objective of this thesis was to evaluate the carcinogenic and non - carcinogenic risk in the human population exposed to radon and lead in the municipality of Lajes Pintadas / RN / Brazil. To meet this objective, analyzes were performed with 123 individuals from the municipality, randomly selected. Results of the social questionnaire survey, analyzes the oral mucosa cells to visualize and compare possible changes caused by contact with lead and radon, as well as blood and urine, to quantify a presence of lead. In homes, people, people, people who had a purpose to quantify radium present in the air. We conclude that the diversity of information and a wide range of concentrations encountered, a great need for research in the region, with a view to assessing the real impact on human health.
