La agricultura ecolgica se caracteriza por utilizar mtodos que potencien la fertilidad natural de los suelos y su capacidad productiva, para lograr su sostenibilidad en el tiempo. Los radionclidos, que se encuentran de forma natural en los suelos, pueden modificar su contenido en terrenos agrcolas por la aplicacin de fertilizantes procedentes de materias primas que de forma natural contienen radionclidos. Los fosfatos, que forman la base habitual de este tipo de abonos qumicos minerales, contienen usualmente cantidades apreciables de uranio y de sus descendientes de las series naturales de desintegracin. Se hace necesario pues encontrar una forma de elucidar de forma fiable si se han utilizado abonos minerales y controlar la incorporacin al suelo y a los cultivos de elementos traza indeseables junto con radionclidos. En este libro se presenta un estudio que pretende discriminar el carcter ecolgico de un sistema de cultivo. La determinacin de los contenidos en diversos radionclidos se realiza mediante espectrometra gamma y alpha. Un protagonismo especial es el que presenta el Polonio210.
