Series Description: TQuarterly reports contain both detailed and summarized information on the activities at Y-12 plant. Reports describe chemical processes, business activities, security concerns, worker protection measures, and monitoring programs. Information specific to mercury is found in sections concerning production and fabrication of lithium deuteride, employee and plant protection, and process development. The employee and plant protection section describes monitoring of mercury exposure and release, including sampling of the plant's water supply and Poplar Creek (measurements reported in gallons/day). Workers exposed to mercury are reported as the number of workers sampled and the percentage of workers exposed. The number of air samples and smears are reported for each quarter and results are given in parts per million (ppm) and milligrams/cubic meter (mg/m3). Mercury vapor air concentrations, reported in (mg/m3) for buildings 9201-4 (Alpha-4) and 9201-5 (Alpha-5) include the number of samples and the percentage of samples that gave abnormal or elevated results. Process development measures are described to improve mercury monitoring and ways to prevent loss of material in mercury recovery. Most quarterly reports also contain photographs of instruments, processing machinery and equipment, buildings, waste storage and treatment areas, and plant grounds.
