Neste trabalho, foi avaliada a exposição de trabalhadores suscetíveis a materiais radioativos de ocorrência natural (NORMs) presentes nas estruturas de uma mina de urânio. Os cenários de exposição computacional foram modelados utilizando o código de transporte da radiação MCNPX2.7.0 e os trabalhadores foram representados por simuladores antropomórficos adultos de referência da Comissão Internacional de Proteção Radiológica (ICRP). O ambiente representado no estudo foi referente à mina de Cigar Lake, Canadá. O simulador antropomórfico feminino foi mais exposto do que o masculino, devido a sua menor distância entre os órgãos radiossensíveis e a fonte principal (o solo). O fator de conversão para dose efetiva, derivado da média das doses equivalentes dos dois simuladores, foi de 1,2 Sv/Gy, que é superior em 70% do valor recomendado pelo Comitê Científico das Nações Unidas sobre os Efeitos da Radiação Atômica (UNSCEAR).
