An ionization chamber consisting of two active volumes in a single enclosure and an auto range changing electrometer covering a dynamic range of 10 to the 8th power are discussed. The tritium monitor is designed to have a reduced sensitivity to tritium contamination, to have a fast response, and to be useful for tritium concentrations of a few micro-Ci/cu m to 10 to the 8th power micro-Ci/cu m.
