Differential monitoring of tritium and carbon-14 compounds

A gaseous sampling system was developed to differentially collect all major volatile forms of tritium and carbon-14 according to chemical class. These chemical forms include: tritiated forms of water, hydrogen and organics; as well as /sup 14/C-containing carbon monoxide, carbon dioxide and organics. Sampling campaigns involving the use of this differential /sup 3/H and /sup 14/C collection system have been successfully conducted at a high level liquid waste solidification plant, at a spent fuel storage facility and in the vicinity of power reactors.
