This correspondence is concerning a quarterly air analysis report taken in the Product Chemical Areas of Building 9212 during the last quarter of 1952. There were 2447 air samples taken during this period. In the C Wing, breathing zone samples taken during the cylinder loading operation continued to show high results. Air contamination levels while removing the cylinder from the dissolver were also above the MPL. The air levels during operations at the green salt glove box were reported as exceeding the MPL for several quarters. The air levels indicated by the samples taken in the C-1 Wing Area were well below the MPL. The uranium-air results at the DDU unloading operation were lower than those reported last quarter. The results in the E Chip Dissolving Area showed that the air levels were improved over those of the last quarter. No breathing zone samples showed a weighted mean result that exceeded the MPL in this area. Ten of the fifteen operations studied in the E-Wing Foundry during the last two quarters gave a higher weighted mean this quarter than during the previous quarter, while five gave a decreased air concentration this quarter as compared to last quarter. The data included is presented by the block method where the description of the operation is written at the top of the block and the sample room or area is listed at the bottom of block.
