Uranium dudes
pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.
Uranium decay chains
Radium is a radioactive chemical element, very dangerous, an alpha radiations emitter; radium is also a source of radon, by decay - radon (gas) is also a radioactive element.
Radium is a radioactive chemical element, very dangerous, an alpha radiations emitter; radium is also a source of radon, by decay - also radioactive and dangerous gas.
From these isotopes decay products are obtained and also ionizing radiations.

Radium is an element; it has no sub-parts. Radium is a radioactive element, so it will slowly and spontaneously decay into other elements.

This isotope is radium-226.

The decay of thorium by alpha decay the resultant nuclide is the element radium. The specific nuclide of radium cannot be determined unless we know which specific nuclide of thorium underwent alpha decay.
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
Nope, but it is a colorless, radioactive, inert gaseous element formed by the radioactive decay of radium.
Polonium and radium isotopes exist in the decay chains of Th-232, U-233, U-235, U-238.
Radium undergoes radioactive decay, specifically alpha decay, to become radon. Radium-226 (226Ra) will undergo alpha decay releasing that alpha particle, which is a helium-4 nucleus, to become radon-222 (222Rn).
