The present invention describes a process for obtaining an activated carbon comprising the steps of: (I) pyrolysis of walnut shell; (II) activation; and (III) impregnation with triethylene diamine. Activated carbon has physical-chemical, textural and surface chemistry characteristics that make it suitable for its effective use as filters in the retention of radioactive isotopes, with retention efficiencies of radioactive methyl iodide of up to 98.1%. The invention also describes its use, for example, in nuclear power plants.

El carbón activado posee unas características físico-químicas, texturales y de química superficial, que lo hacen adecuado para su empleo eficaz como filtros en la retención de isótopos radiactivos, con eficiencias de retención de ioduro de metilo radiactivo de hasta el 98,1%. La invención describe asimismo su empleo por ejemplo en centrales nucleares.
