What is radon-222? Radon is considered to be the second leading cause of lung cancer, and is an underrated threat. Testing for radon in structures is a bit tedious, but it can be done. If there is a question about a radon threat to your home, testing is not outrageously expensive.ranium is the source of radium, and from radium we see radon. Uranium is present in the ground in a number of types of rock, so radon could appear in soil samples, in ground water, or in the lower internal spaces in buildings (because is seeps in).

It's Elemental A single gram of radium-226 will produce 0.000l milliliters of radon a day. Radium is about one million times more active than uranium. The lab notebooks used by the Curies are too highly contaminated to be safely handled today.

Radon Fact Sheet Radon is a naturally occurring radioactive gas and comes from the natural breakdown (radioactive decay) of uranium. It is usually found in igneous rock and soil, but in some cases, well water may also be a source of radon.

- (Thorium is…, itself, the radioactive daughter of uranium.) Radium (226Ra, the isotope that is the result of the alpha decay of thorium) has a half-life of 1602 years, and the element acts chemically like the other +2 elements in group 2 of the periodic table. It is highly radioactive and dangerous.

- Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless[2] noble gas. It occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead; radon, itself, is a decay product of radium. Its most stable isotope, 222Rn, has a half-life of 3.8 days.

Learning Objectives Radon is a naturally occurring, gaseous element that is a by-product of the radioactive decay of another element, uranium. When an atom of uranium decays to radon it does so by transforming itself into a series of different radioactive elements, each a decay by-product of the preceding one.The series passes ultimately through radium directly to radon, which, in turn, decays to other elements.hen an atom of uranium decays to radon it does so by transforming itself into a series of different radioactive elements, each a decay by-product of the preceding one.

- Radon is a tasteless, odorless, invisible gas that occurs naturally throughout the earth's crust. It is a by-product of the breakdown of uranium in the soil, rock, and water. Over time, uranium will decay into lead. This process has fourteen steps, and radon is formed at the sixth step.

Health effects of radon Radon is formed as part of the normal radioactive decay chain of uranium into 206Pb. Uranium has been present since the earth was formed and its most common isotope has a very long half-life (4.5 billion years), which is the time required for one-half of uranium to break down.

Radon Three other radon isotopes have a half-life of over an hour: 211 Rn, 210 Rn and 224 Rn. The 220 Rn isotope is a natural decay product of the most stable thorium isotope (232 Th), and is commonly referred to as thoron. It has a half-life of 55.6 seconds and also emits alpha radiation.t is a radioactive, colorless, odorless, tasteless noble gas, occurring naturally as a decay product of radium. Its most stable isotope, 222Rn, has a half-life of 3.8 days. Radon is one of the densest substances that remains a gas under normal conditions.

Radon and Cancer Radon is a colorless, odorless, radioactive gas. It forms naturally from the decay (breaking down) of radioactive elements, such as uranium, which are found in different amounts in soil and rock throughout the world.adon breaks down into solid radioactive elements called radon progeny (such as polonium-218, polonium-214, and lead-214). Radon progeny can attach to dust and other particles and can be breathed into the lungs.

RADON Radon was discovered by Robert Bowie Owens and Ernest Rutherford (GB) in 1899. The origin of the name is variation of the name of element radium; radon was called niton at first, from the Latin word nitens meaning shining. It is a colourless, odourless radioactive, heavy, noble gas that is chemically inert and non-flammable but is highly radiotoxic and carcinogen by inhalation. Radon is formed from the decay of radium in the earths crust. It is used to treat some forms of cancer. PHYSICAL PROPERTIES.

- Radon is a naturally-occurring radioactive gas that comes from radioactive decay of uranium and radium deposits in soil, rocks, and well water. You cannot see it, taste it, or smell it. Radon gas atoms decay into solid radioactive atoms called “Radon daughters” (sometimes referred to as “Radon progeny”) . It is the Radon daughters in inhaled air that can deposit in our lungs and cause health problems.

It's Elemental The glow becomes orange-red as the temperature is lowered. Radon's most stable isotope, radon-222, has a half-life of about 3.8 days. It decays into polonium -218 through alpha decay. Small amounts of radon are sometimes used by hospitals to treat some forms of cancer. Radon fluoride (RnF) is the only confirmed compound of radon.

- Radon is a gas that occurs naturally from the breakdown—or the radioactive decay—of uranium. Rocks, soil, and in some cases groundwater can all contain uranium.Because radon comes from so many sources, people are easily exposed to it.adon is an odorless, colorless, radioactive gas. It is also the second leading cause of lung cancer in the United States.
