Abstract

LA INVENCION SE REFIERE A UN GEL CAPAZ DE RETENER UNA CONTAMINACION RADIACTIVA Y SU UTILIZACION PARA PROTEGER O DESCONTAMINAR SUPERFICIES. ESTE GEL ESTA CONSTITUIDO POR UNA SOLUCION ACUOSA COLOIDAL QUE COMPRENDE 2,5 A 155 EN PESO DE UN AGENTE GELIFICANTE Y 5 A 155 EN PESO DE UN AGENTE FILMOGENO CON EVENTUALMENTE UNO O VARIOS ADITIVOS ELEGIDOS ENTRE LOS AGENTES CONSERVANTES (0,2 A 1%), LOS AGENTES ANTIESTATICOS (0,5 A 1,5%), LOS COPOLIMEROS ACRILICOS (O,1 A 8%), LOS COLORANTES (0,001 A 1%) Y LOS AGENTES ADSORBENTES (1 A 5%). ESTOS GELES PUEDEN APLICARSE FACILMENTE SOBRE LA SUPERFICIE A PROTEGER O A DESCONTAMINAR Y A CONTINUACION ELIMINARSE CON LA RADIACTIVIDAD QUE HAN FIJADO, CON UN SENCILLO LAVADO CON AGUA.THE INVENTION REFERS TO A GEL CAPABLE OF RETAINING RADIOACTIVE CONTAMINATION AND ITS USE TO PROTECT OR DECONTAMINATE SURFACES. THIS GEL IS CONSTITUTED BY A COLLOID AQUEOUS SOLUTION WHICH INCLUDES 2.5 TO 155 IN WEIGHT OF A GELING AGENT AND 5 TO 155 IN WEIGHT OF A FILMOGENIC AGENT WITH EVENTUALLY ONE OR VARIOUS ADDITIVES CHOSEN AMONG THE PRESERVATIVE AGENTS (0.2 TO 1% ), ANTI-STATIC AGENTS (0.5 TO 1.5%), ACRYLIC COPOLYMERS (OR, 1 TO 8%), COLORANTS (0.001 TO 1%) AND ADSORBENT AGENTS (1 TO 5%). THESE GELS CAN BE EASILY APPLIED TO THE SURFACE TO PROTECT OR DECONTAMINATE, AND THEN REMOVE WITH THE RADIOACTIVITY THEY HAVE FIXED, WITH A SIMPLE WASH.
