    Radon is a chemical element; it has symbol Rn and atomic number 86. It is a radioactive noble gas and is colorless and odorless. Of the three naturally occurring radon isotopes, only 222 Rn has a sufficiently long half-life (3.825 days) for it to be released from the soil and rock where it is generated.

  3. 27 wrz 2024 · radon (Rn), chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium. (Radon was originally called radium emanation.) Radon is a colourless gas, 7.5 times heavier than air and more than 100 times heavier than hydrogen.

  4. 18 sie 2023 · Chemical elements which decay into radon, such as uranium, thorium and radium can be present in soil, water and construction materials. IAEA safety standards establish concentrations of radon in homes and at workplaces to protect the people’s health.

  5. Radon is a colorless, odorless and tasteless gas which makes it presence hard to detect by humans. Radon seeps up through the ground and diffuses into air. Radon exhibits brilliant yellow phosphorescence at temperature below its freezing point.

  6. 25 sty 2023 · Radon is a naturally occurring radioactive gas which may be found in high concentrations in indoor environments, such as homes and workplaces. Radon is one of the leading causes of lung cancer. Radon is estimated to cause between 3% to 14% of all lung cancers in a country, depending on the national average radon level and smoking prevalence.

  7. The element generally used was fluorine, the most active chemical element. The result was the formation of noble gas compounds. The first radon compound to be produced was radon fluoride (RnF).
