Source sentences:
text: The heavy isotopes 266Rf and 268Rf have also been observed as electron capture daughters of the dubnium isotopes 266Db and 268Db, but have short half-lives to spontaneous fission: it seems likely that the same is true of 270Rf, a likely daughter of 270Db.
text: Only small amounts of rutherfordium have ever been produced and its isotopes have very short half-lives.
