Abstract
Para ello se elimina inicialmente una capa de oxido de la pieza metálica con una solucion descontaminante. Se prevé eliminar luego un medio con efectooxidante todavía presente en la solucion descontaminante. Como consecuencia se extrae una capa deme tal. Dado que los radionuclidos se encuentran solo en lacapa cercana a la superficie de la pieza metálica, el metal residual puede ser conducido a una eliminacion convencional.
