Santiago Ripol<\/strong><\/a>, acad\u00e8mic em\u00e8rit de la Reial Acad\u00e8mia Europea de Doctors-Barcelona 1914<\/strong> (RAED), alerta sobre la contaminaci\u00f3 radioactiva que s’ha instal\u00b7lat a la cadena aliment\u00e0ria i insta els governs i la societat civil a reflexionar sobre un assumpte que no acostuma a ser a l’agenda p\u00fablica. L’acad\u00e8mic fa aquestes reflexions al seu treball “Un riesgo permanente: la contaminaci\u00f3n radioactiva de los alimentos”<\/strong>, que ser\u00e0 publicat a la pr\u00f2xima entrega de Tribuna Plural<\/strong>, la revista cient\u00edfica de la RAED.<\/p>\n

“Tot i que les dosis de radiaci\u00f3 ingerides siguin baixes, aquest tipus de contaminaci\u00f3 t\u00e9 un alt efecte toxicol\u00f2gic perqu\u00e8 l’organisme no t\u00e9 mecanismes espec\u00edfics de defensa contra la radiaci\u00f3, sense comptar que ni tan sols \u00e9s capa\u00e7 de detectar-la, i que alguns \u00f2rgans o teixits presenten alguna afinitat amb certs radion\u00faclids que poden fixar-se i acumular-se si la font contaminant persisteix -assegura Ripol-. Alguns radion\u00faclids tenen una vida mitjana molt curta, de manera que nom\u00e9s representen un risc puntual en cas d’accident, per\u00f2, per contra, altres tenen una vida mitjana raonablement llarga o molt llarga, i es converteixen en contaminants permanents”.<\/p>\n

L’acad\u00e8mic assenyala les caracter\u00edstiques i les fonts de contaminaci\u00f3 dels radiois\u00f2tops m\u00e9s significatius i presents en el medi ambient: iode, estronci, cesi, ferro i ruteni, i apunta els quatre principals factors de risc i les pol\u00edtiques que podrien minimitzar: pol\u00b7luci\u00f3 del s\u00f2l i de les aig\u00fces, pol\u00b7luci\u00f3 atmosf\u00e8rica, transformaci\u00f3 de la flora i de la fauna i transformaci\u00f3 de la geomorfologia a trav\u00e9s de la industrialitzaci\u00f3, la urbanitzaci\u00f3 i el creixement demogr\u00e0fic. “Aquests quatre factors representen el tribut gaireb\u00e9 obligat que hem de pagar per la civilitzaci\u00f3 i es troben profundament relacionats amb la progressiva degradaci\u00f3 del medi. Una altra q\u00fcesti\u00f3 per dilucidar seria si el progr\u00e9s que experimentem compensa i justifica l’exc\u00e9s de contaminaci\u00f3 ambiental, o b\u00e9 si seria possible reduir significativament aquesta contaminaci\u00f3, almenys en part”, clou Ripol.<\/p>\n","protected":false},"excerpt":{"rendered":"
