How is radon used in medicine?

How is radon used in medicine?

Radon decays into radioactive polonium and alpha particles. This emitted radiation made radon useful in cancer therapy. Radon was used in some hospitals to treat tumours by sealing the gas in minute tubes, and implanting these into the tumour, treating the disease in situ.

Are there any benefits to radon?

An active Radon system in the home offers major advantages, such as: Improving the indoor air quality. Reducing the moisture content in the air before it enters the home. Aids in inhibiting moisture that otherwise accumulates in slab or basement floors.

What is radon therapy?

The therapeutic use of radon involves the intake of radon gas either through inhalation or by transcutaneous resorption of radon dissolved in water.

How is radon used today?

It is used in the treatment of cell damage and cancer. Radon is also used in radiation therapy.

What is radon radiation?

Radon is a radioactive gas that forms naturally when uranium, thorium, or radium, which are radioactive metals break down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes.

When did radon become a health problem?

In the 1950s radon was recognized as an indoor air pollutant, prompting further research into its health effects in the 1970s. The research clearly labeled radon as a carcinogen, but it wasn’t until 2005 that U.S. Surgeon General, Richard H.

Where does radon come from in a home?

Radon is a radioactive gas. It comes from the natural decay of uranium that is found in nearly all soils. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up.

What health problems does radon cause?

Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer. Radon is responsible for about 21,000 lung cancer deaths every year. About 2,900 of these deaths occur among people who have never smoked.

What does radon combine with?

Radon gas does not react with halogens other than fluorine. It seems that radon gas reacts with fluorine to form the difluoride radon(II) fluoride, RnF2, but the compound is not properly characterized.

How does radon become radioactive?

Radon is a colorless, odorless gas, a radioactive byproduct of radium. In summary, a radon atom in the air decays within a few days into its short-half-life radon daughters, which decay within about an hour; with these decays, three alpha particles are emitted, one by radon and two by its daughters.

How is radon used to treat cancer?

Radon decays into radioactive polonium and alpha particles. This emitted radiation made radon useful in cancer therapy. Radon was used in some hospitals to treat tumours by sealing the gas in minute tubes, and implanting these into the tumour, treating the disease in situ.

Can radon cure cancer?

Radon was once commonly used to treat cancer too. The radiation it gives off kills cancer cells. However, the element must be used with great care because radiation can kill healthy cells as well. In fact, the bad side-effects of radiation therapy are caused by the killing of healthy cells by radiation.

Does radon increase your risk of lung cancer?

When you breathe in radon, radioactive particles from radon gas can get trapped in your lungs. Over time, these radioactive particles increase the risk of lung cancer. It may take years before health problems appear. People who smoke and are exposed to radon are at a greater risk of developing lung cancer .

How risky is radon for causing lung cancer?

The EPA estimates that radon exposure increases lung cancer risk eight to nine times in smokers compared with nonsmokers. Major scientific organizations believe that radon contributes to approximately 12% of lung cancers annually in the United States.
