A radioactive gas, formed from the radioactive decay of radium, and used in capsules called radon seeds to treat cancers inside the body.
Radioactive, gaseous, nonmetallic element, used in radiotherapy. Elevated levels of radon gas have been detected in homes in some areas. The need for its removal, although recommended by, for example, the Environmental Protection Agency, is the subject of much scientific controversy.
A colorless, gaseous, radioactive element produced by the disintegration of radium, uranium, lead, zinc, and iron ore. Radon is thought to cause an increase in lung cancer when found in microscopic particles in environmental airborne dust. It is odorless, colorless, tasteless, and not irritating to the lungs, which is why it is important for people to get their homes tested for radon. It is believed that 11 percent of lung cancer cases are related to radon. Radon is used in radiation therapy.
A radioactive gaseous element that is produced during the decay of radium. Sealed in small capsules called radon seeds, it is used in radiotherapy for the treatment of cancer. It emits alpha and gamma radiation.
A radioactive gaseous element resulting from the disintegration of isotopes of radium; atomic weight 222, atomic number 86. Because radium is present in the earth’s crust, radon and its disintegration products accumulate in caves, mines, houses (particularly those that are energy efficient), and any space where no free exchange exists between the air contained in it and the air outside it. Exposure to radon above acceptable limits is believed to be a risk factor for lung cancer.
A radioactive, colorless, odorless, and tasteless gaseous element is generated through the radioactive decomposition of radium.
A byproduct resulting from the decay of radium, this element is a colorless, gaseous, and radioactive substance.
