The end product of the decay chain that starts with Uranium-238 is what?

The decay chain that begins with Uranium-238 ultimately leads to the formation of Lead-206 as its stable end product. This process involves a series of alpha and beta decays through various intermediate isotopes, including Radon-222 and Polonium-214, before reaching Lead-206.

Understanding this decay chain is crucial, especially because Radon-222, which can pose health risks due to its radioactive nature, is one of the intermediate products. However, the focus on the final stable nucleus—Lead-206—is significant because it is non-radioactive and considered the end of the decay process for Uranium-238. The presence of Radon-222 and Polonium-214 highlights the transitional phases that occur before achieving stability with Lead-206. Therefore, knowing that Lead-206 is the stable product at the end of this decay sequence is essential in discussions regarding radon measurement and radioactive decay processes.
