radon
Naturally radioactive promethium was briefly used as a replacement for radium in self-luminous paint. It is element 61.
Helium is a natural element that is extracted from underground gas deposits through a process called helium mining. It is not synthetic, but rather a naturally occurring element found in the Earth's crust.
Marble itself is not inherently radioactive, as it is primarily composed of calcium carbonate. However, certain deposits of marble may contain trace amounts of naturally occurring radioactive elements such as uranium and thorium, which can contribute to its radioactivity. It is always a good idea to check the specific source of marble if you have concerns about its radioactivity.

Some isotopes are radioactive, some are not.
It is radioactive decay.
This phenomenon is called radioactive disintegration.
A geothermal underground pool is typically referred to as a hot spring or a thermal spring. These pools are naturally heated by underground geothermal sources, such as magma chambers, and are enjoyed for their relaxing and therapeutic properties.

No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
The process by which some substances spontaneously emit radiation is called radioactive decay. During this process, unstable atomic nuclei release particles (such as alpha or beta particles) or electromagnetic radiation (such as gamma rays) to achieve a more stable configuration.
Something that is radioactive is called a radionuclide.
Some isotopes are radioactive, some are not.
