Sonia Cotelle (Fuente: Muse\u00e9 Curie)<\/figcaption><\/figure>\n<\/div>\n\n\n

Diplomada en qu\u00edmica general, biol\u00f3gica y aplicada en la Universidad de la Sorbona (Francia), se especializ\u00f3 en fuentes radiactivas.<\/p>\n\n\n\n

En 1919, comenz\u00f3 su trabajo como investigadora incorpor\u00e1ndose al equipo de la cient\u00edfica Marie Curie<\/a> en el Institut du Radium (actual Museo Curie) de Par\u00eds (Francia).<\/p>\n\n\n\n

Entre 1926 y 1927 investig\u00f3 sobre el polonio y el actinio en colaboraci\u00f3n con Marie Curie. Asimismo, determin\u00f3 la semivida o el tiempo de vida medio del ionio, el nombre por el que se conoc\u00eda al torio-230 en aquella \u00e9poca.<\/p>\n\n\n\n

Durante su etapa en Checoslovaquia, donde vivi\u00f3 entre 1927 y 1936, Cotelle determin\u00f3 el n\u00famero at\u00f3mico del polonio por espectroscopia de rayos X<\/a>. <\/p>\n\n\n\n
