What are the daughter products of radon decay?

The daughter products of radon decay consist of a series of radioactive isotopes, primarily polonium, bismuth, and lead. When radon-222, a common isotope of radon, decays, it follows a decay chain that results in these specific elements being formed. Each of these daughter products can further decay into other elements or isotopes, but polonium, bismuth, and lead are the immediate products of radon's decay process.

Understanding this decay chain is crucial in environmental health, as radon is a significant concern due to its radioactive properties and potential health risks, particularly its association with lung cancer. The other options do not reflect the accurate elemental products of radon decay, focusing instead on entirely different elements or processes that are not directly related to the decay of radon itself.
