text: Out of isotopes whose half-lives are known, the lighter isotopes usually have shorter half-lives; half-lives of under 50 μs for 253Rf and 254Rf were observed.

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: While the isotope 264Rf has yet to be observed, it is predicted to have a short half-life of 5 s.

text: While the isotope 264Rf has yet to be observed, it is predicted to have a long half-life of 1 h. Before its discovery, 265Rf was predicted to have an even longer half-life of 13 h, but it has a half-life of only 2.5 min.
