Which of the following are daughter products of radon?

Radon is a naturally occurring radioactive gas that is part of the decay chain of uranium. When radon undergoes radioactive decay, it produces several daughter products, also known as decay products. These daughter products include isotopes such as polonium, lead, and bismuth.

In the decay sequence, radon-222 decays primarily into polonium-218, which subsequently continues to decay into lead-214 and bismuth-214, along with several other isotopes before reaching a stable state. This series of decay produces solid particles that can be inhaled and retained in the lungs, which is a significant health hazard associated with radon exposure.

Other options do not represent the correct daughter products since they involve elements that are not part of radon's decay chain. Understanding radon and its decay products is crucial for environmental health specialists, particularly when assessing risks associated with radon exposure in homes and buildings.
