Lead 206 (Pb)
lead
Radon is a natural chemical element; it can be found inthe radioactive decay series of uranium, thorium.
Actinium is a natural chemical element, radioactive; actinium is a decay product of uranium.
Radon is a radioactive noble gas. It is a decay product of radium, which is part of the decay series for uranium. Since uranium is a naturally occurring element, it comes from all over the world, not just from Italy.
Uranium itself is a radioactive and toxic element. All the elements from the decay chain of uranium isotopes are also radioactive (ex.: radon, radium, etc.) excepting the final product, an isotope of lead.
Uranium decay chains
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
Lead, the isotope Pb 206.
The end products of uranium isotopes decay chain are the isotopes of lead.
Radon is a natural chemical element; it can be found inthe radioactive decay series of uranium, thorium.
Actinium is a natural chemical element, radioactive; actinium is a decay product of uranium.
Radon is a radioactive noble gas. It is a decay product of radium, which is part of the decay series for uranium. Since uranium is a naturally occurring element, it comes from all over the world, not just from Italy.
The uranium decay chain ends with lead stable isotopes.

Uranium decay chains
Uranium itself is a radioactive and toxic element. All the elements from the decay chain of uranium isotopes are also radioactive (ex.: radon, radium, etc.) excepting the final product, an isotope of lead.
It is thorium 234.
A stable, nonradioactive atom must be formed.
