Isotopes of radon are more dangerous than the natural isotopes of uranium.
The specific activity of Am-241 is 3,4 Ci/g.
The specific activity of Rn--222 is 1,5.10e+5 Ci/g.
The difference is formidable !
well thats a hard question
Radon is a gas, possible to be in buildings. Radon 222 is an isotope of radon, the most common.

Radon-222 undergoes alpha decay to produce polonium-218as a daughter.

For example, many smoke detectors have minute amounts of americium-241. This is not really a health problem, due to the tiny amounts.Just about any home has radon-222, which in turn is emitted by radioactive decay of uranium and thorium. Some homes have more of it than others - depending on the building materials - and this IS a health concern. Radon is the second cause of lung cancer.
Radon has four main isotopes: 210Rn, 211Rn, 222Rn, and 224Rn. Radon-222 is the most stable form.
When radium-226 decays to form radon-222, the radium nucleus emits a alpha particle.
Radon has atomic mass of 222. There is isotope of Radon with mass number 226. Radon is a Nobel gas.
