Portable monitor for tritium in air
A portable monitor has been developed which accurately measures tritium concentrations between 1 x 10/sup -4/ and 1 x 10/sup -1/ ..mu..Ci/cc of air. The instrument consists of five basic sections: air pump, deionizer, ionization chamber, logarithmic electrometer amplifier, and high voltage power supply. An internal rechargeable 12-volt battery powers the entire monitor. A connector is provided so that an external 12-volt battery can be used if the monitor is needed for extended periods of time. Total weight of the unit is 22 pounds and the overall dimensions are 10.5 x 6.8 x 13.2 inches. The instrument has been calibrated by comparison with a Kanne monitoring system and evaluated under varying levels of tritium activity. Readings were reproducible within +-10% of reading. 7 refs., 5 figs.
