Source sentences:
text: Although it wasn't spotted until it had already been made in reactors, neptunium does actually exist in a natural form on the earth, when uranium undergoes the process that takes place in a reactor, capturing a neutron from another uranium atom that has split, and emitting a beta particle to transmute it to neptunium - but this only happens in the tiniest quantities.
text: Np will capture a neutron to formNp and beta decay with a half-life of 2 days toPu.
