Gases emitted by the radium substance are collected in a glass tube. Oxygen, nitrogen, water vapor, carbon dioxide, and other gases are eliminated from the gas in television. All isotopes of radon have short half-lives as well as do not stay in the environment long. The half life of a contaminated aspect or isotope is the moment it takes for fifty percent of an example of the aspect or isotope to damage down.
