It means that the corresponding element (or isotope) is unstable; the atoms will decay eventually.
Yes, radon is a decay product in the uranium, thorium and actinium decay series.
The problems are:- radioactivity and toxicity of uranium- release of radon- generally low concentration of uranium in rocks- possible contamination of the environment
Several examples are uranium, thorium, radon, actinium, protactinium, plutonium, americium, etc.
Uranium is a chemical element, toxic and radioactive. 1. Uranium is a possible polluting agent of the natural environment, lands and waters. 2. Uranium release radium and radon. Radon is also dangerous by inhalation - being a cause of some lung cancers. 3. The radioactivity of the environment is increased. 4. The contamination of living organisms can be harmful above a certain limit.
Radon daughters are the products of uranium decay.

Uranium and thorium minerals contain radon.
If the questioner means radon then it is by uranium decomposing

Immediately after the discovery of the radioactivity of radon, near 1900.
Radon exist in rocks containing uranium or thorium.
The radioactivity of natural uranium is not so important. The external irradiation is very low. But the internal irradiation is dangerous: alpha radiations from inhaled uranium, radium and radon (Ra and Rn released by decay from U) can destroy pulmonary alveoli and cause lung cancers. Also the ingestion is dangerous because soluble salts of uranium are toxic.
Radon daughters are the products of uranium decay.
All radon isotopes are radioactive and unstable; the radioactivity is not dependent on temperature.
