Is zircon radioactive?

Zircon sometimes contains traces of uranium238, and it can be very slightly radioactive at levels that pose no health risk when used in jewelry.

uranium and thorium in zircon

Uraniumlead dating, unlike the uraniumthorium dating described above, looks for an end product of the decay of uranium238 or lead207 from uranium235, this product being lead208 Because Zircon does not naturally incorporate lead atoms into its structure, it can be assumed that the lead content in Zircon is the product of uranium.

Zircon Chronology: Dating the Oldest Material on Earth | AMNH

Zircon contains the radioactive element uranium, which Dr. Mueller calls “the clock within the zircon” because it converts to the element lead at a specific rate over a long span of time. According to Mueller, this makes zircons “the most reliable natural chronometer that we have when we want to look at the earliest part of Earth history.”
