Uses and Colors
- Radon is still produced for therapeutic use by a few hospitals by pumping it from a radium source and sealing it in minute tubes, called seeds or needles, for application to patient. This practice has been largely discontinued as hospitals can get the seeds directly from suppliers, who make up the seeds with the desired activity for the day of use.
- At normal room temperatures, radon is a colorless, odorless, radioactive gas.
Elements in its group
- Other elements in radon's group are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), and Xenon (Xe)
