Depleted Uranium
Caesium-137 as it decays by beta emission.
Thorium can be used as fertile material (as ThO2) in nuclear power reactors; is a precursor of the fissile isotope 233U. This type of reactor is called a breeder: the reactor produce more fissile material than it consumes. It is a very strange and important characteristic.
All of the praseodymium ordinarily found in nature is of a single stable isotope, 141Pr. Like all other elements, there are synthetic radioactive isotopes of praseodymium.
Yes, americium is a radioactive metal. This element has no stable isotopes.
Most metals are stable and thus not radioactive.
Uranium is a radioactive element; the isotope 235 is fissile with thermal neutrons; the isotope 238 is not so fissile but is fertile (transformation in the fissile isotope plutonium 239). Consequently, uranium is a good nuclear fuel and also can be used in nuclear weapons.

Yes. Uranium is a radioactive metal
It is diatomic. Being radioactive, and its most stable isotope having a half life of 8.3 hours, it is usually not considered.
Berkelium is a metal, solid, member of the actinoids group, radioactive, artificial, atomic number 97, the isotope with the longest half life is 247Bk, etc.
No: Iodine is not a metal at all, but a nonmetal. It is not necessarily radioactive, but has some radioactive isotopes.
Yes, americium is a radioactive metal. This element has no stable isotopes.
Darmstadtium is a radioactive metal but supplementary data are not known.
No. Radon is a radioactive noble gas.
Yes, uranium is a radioactive metal.
