6. Upon analysis of these samples, it was noted that the quench factor (SQP(E) #) was outside of the useful calibration range for this analysis. Thus, an approximate volume of 10 μL of nitro-methane was added to the samples and associated QC to bring them into the usable calibration range. 7. ICP-AES measurement of lead carrier concentrations prior to chemical separation for most samples in this work order showed concentrations less than the amount known to have been added to the samples in the form of lead carrier. To avoid a low bias in the final analytical results the known concentration of the carrier was used in chemical yield calculations in lieu of the pre- separation measurement. These samples are identified with an "LB" flag on the Radiochemistry ICP Worksheet, which can be found in Section 5 of this report. 8. In the analysis of the raw data, "Window 2" is monitored for high-energy beta contamination. Sample 0805200-2 had a "Window 2" count rate slightly above the upper control limit of 0.73 cpm at 0.737 cpm, established from calibration on 06/11/08 through 06/16/08. The sample had observed activity at a level below the achieved MDC. It is believed that the data quality is unaffected and the results are submitted without further qualification. 9. The requested detection limit of 1.0 pCi/gram was not met for samples 0805200-4 and -12. The observed activity for these samples is above the achieved detection limit, as indicated on the final reports by an 'M3' qualifier. Results are submitted without further qualification.
