Hydrogen is an excellent absorber of neutrons and gamma radiation. In water, it is *very* common as a shielding material. Cobalt-59 is used as a neutron absorber for some nuclear reactors (control rods), and makes a radioactive material useful in industry and medicine (Co-60). Zirconium can accept many neutrons before becoming radioactive itself. It is commonly used to package materials used in the nuclear industry. Uranium-238 is an excellent shield for gamma radiation sources, requiring less total mass than an equivalent amount of lead. Or you could just use Lead to stop radiation, which is probably the boring answer you were looking for. Note that no element is a "shield from radioactive substances", just for line-of-sight radiation from them. Radiation from plutonium-239 is most dangerous when it has been inhaled into your lungs. Lead won't help here. Radiation from Strontium-90 damages your bone marrow when ingested with food. Lead won't help here either.

Lead mainly, in some cases (ironically) depleted uranium, a few others do the job but those are the main two you'll find

Usually lead. It's the most stable, and densest material known to prevent radiation escaping.
