Tritium (3H) in air exists mostly as water vapor (H1H3O) or gaseous hydrogen (H1H3). Due to the short range of beta particles emitted by tritium (only a few millimeters in air), windowless counter tubes must be used, ie the air to be measured is added to the count gas. Therefore, for continuous measurements, the counter tube must be run in flow-through mode
