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.

Radioactive substances are typically stored in secure containers that shield against radiation. These containers are often placed in controlled environments with regulated access to prevent exposure to individuals. Additionally, some radioactive materials may require specific temperature, humidity, or ventilation conditions for safe storage.
* Alpha radiation can be stopped by a sheet of card * Beta radiation can be stopped be a few inches of aluminium * Gamma radiation can be stopped by several inches of lead or many feet of concrete.
radioactive decay
The radioactive element that begins with the letter R is radium. Radium is a highly radioactive element and is found in uranium ores. It emits alpha, beta, and gamma radiation.
Lead is commonly used as a shield to protect people from radioactive substances. It is dense, so it effectively absorbs and blocks the radiation, helping to minimize exposure to harmful radiation._lead

Lead
It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.

A radioactive element is an element that has an unstable nucleus, leading to the emission of radiation in the form of alpha, beta, or gamma particles. This emission is a result of the element's attempt to achieve a more stable configuration. Common examples of radioactive elements include uranium, thorium, and radium.
non radioactive element
Radioactive substances are typically stored in secure containers that shield against radiation. These containers are often placed in controlled environments with regulated access to prevent exposure to individuals. Additionally, some radioactive materials may require specific temperature, humidity, or ventilation conditions for safe storage.
Radioactive substances are the things that put off radiation. These could be radioactive waste, or even radioactive materials not yet used.
* Alpha radiation can be stopped by a sheet of card * Beta radiation can be stopped be a few inches of aluminium * Gamma radiation can be stopped by several inches of lead or many feet of concrete.
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
Usually lead is used for shielding, however I believe Boron is used to in a sense "neutralize" radioactive material. I believe this was discussed in possible solutions for Fukashima
