- n. A lustrous, grayish-white, strong, ductile metallic element obtained primarily from zircon and used chiefly in ceramic and refractory compounds, as an alloying agent, and in nuclear reactors as a highly corrosion-resistant alloy. Atomic number 40; atomic weight 91.22; melting point 1,852°C; boiling point 4,377°C; specific gravity 6.56 (20°C); valence 2, 3, 4. See Table at element.

It isn't quite what I want though, because the disintegrating rays which the ring discharge gives out break down the zirconium, which isn't an end-product of radioactivity.
The zirconium is a dual-use metal used for the production of nuclear reactor pipes.
Thus, top-ranking Bulgarian officials are said to have committed document fraud and other crimes with regard to "the transfer and the very likely sale" of 10 tons of zirconium, which is a dual-use metal.
The most efficient piezoelectric material known is PZT, a compound of lead, zirconium, and titanium.
The highest concentration of fission products are contained within the zirconium cladding.
The fuel rods must be removed, not when all the fission fuel has been used up, but far earlier, when the zirconium begins to crack from the exposure to radiation, threatening to release radioactive gasses building up in the core.
The fuel is uranium oxide, 97% of which is U-238 and 3% U-235 useful for making bombs, which is encased in zirconium tubes.
If the rods are partially or fully uncovered, at around 1000 degrees steam interacts with the zirconium cladding to form hydrogen.
The gas is a product of the breakdown of zirconium cladding that encases fuel rods.
If the core heats up enough, the zirconium cladding around the core causes the water to release hydrogen.
