Abstract

PARA DESCONTAMINAR UNA SUPERFICIE RADIACTIVA, SE PROPONE BARRERA ESTA SUPERFICIE (10) MEDIANTE UN HAZ LASER ENFOCADO (21), EN PRESENCIA DE UN LIQUIDO (29) TAL COMO EL AGUA, O PREFERENTEMENTE, UNA SOLUCION DE ACIDO NITRICO SOBRE TODA ESTA SUPERFICIE. EL LIQUIDO (29) PUEDE PARTICULARMENTE PRESENTARSE EN FORMA DE UNA PELICULA QUE FLUYE SOBRE LA SUPERFICIE Y SE RECICLA VENTAJOSAMENTE. SE OBTIENE ASI UNA DESCONTAMINACION MUY EFICAZ.TO DECONTAMINATE A RADIOACTIVE SURFACE, THIS SURFACE (10) IS PROPOSED TO BE BARRIED BY A FOCUSED LASER BEAM (21), IN THE PRESENCE OF A LIQUID (29) SUCH AS WATER, OR PREFERABLY, A NITRIC ACID SOLUTION ON ALL THIS SURFACE. THE LIQUID (29) MAY PARTICULARLY BE PRESENTED IN THE FORM OF A FILM THAT FLOWS OVER THE SURFACE AND IS ADVANTAGELY RECYCLED. SO A VERY EFFECTIVE DECONTAMINATION IS OBTAINED.
