| Summary: | (LANL), the Los Alamos Neutron Science Center (LANSCE) has analyze scrubber performance with an BPGE detector. and downstream of the scrubber were collected on a carbon by 29%. The scrubber effectiveness at removing tritium was carbon dioxide. The highest removal effectiveness of the catalytic conversion to convert all carbon in the air to conversion of all carbon forms to C02- delay line was constructed to delay exhaust air releases, and Different scenarios were examined with this model system, dioxide absorber and analyzed with a sodium iodide detector. dose equivalent annually. At Los Alamos National Laboratory effectiveness to be greater than 95%. Removal of carbon- I I facility must be limited so that no member of the public found by collecting grab samples of the air stream on silica gel, both upstream and downstream of the scrubber. Results implemented engineering controls to ensure that emissions including varying the pH of the scrubber water and using ionization chamber and high-purity germanium (HPGE) detector, model system was greater than 95%, under high pH and complete of liquid scintillation analysis show the tritium removal radioactive airborne effluents from a Department of Energy receives more than 0. IO miflisievert (IO milhrem) effective release. Also, an air scrubber was built at the beam stop to remain below this limit. At the accelerator beam stop, a remove excess water, acids, triti@ and carbon dioxide from the air stream. This thesis describes the effectiveness of the delay line was shown to reduce overall facility emissions The second method used a bench-top model scrubbing system to thereby allow for decay of any radioactivity prior to these emissions control efforts. Using a flow-through Under federal regulations set forth in 40 CFR 61, releases of was determined by two methods. First, air samples upstream |
