CONT

El uranio-235 y el plutonio-239 son los materiales físiles normalmente utilizados en la producción de explosivos nucleares. Otros materiales físiles potencialmente utilizables incluyen el uranio-233, el americio, el neptunio y otros isótopos del plutonio.

OBS

No confundir con "material fisionable".

OBS

material fisionable: Material susceptible de ser fisionado cuando es bombardeado por neutrones o fotones de la energía apropiada. El uranio-238, por ejemplo, es fisionable pero no físil.
