[...] el interés principal del torio [...] resulta de su calidad de materia fértil: expuesto al flujo de neutrones rápidos en el seno de un reactor autorregenerador, el torio 232 absorbe un neutrón y se convierte en torio 233, el cual, mediante emisión de una partícula beta se convierte en proactinio 233 que, por pérdida de otra partícula beta, da uranio 233, isótopo éste que es físil y puede servir como combustible nuclear en otro reactor. 4, record 2, Spanish, - torio
