Notes: 1. LLDs are a-priori values.

2. MDCs are calculated a-posteriori values.
3. Gamma spectroscopy analysis results are calculated from a measurement using only one gamma energy line.
4. Air sample volumes are received in units of ft3. GEL converts the units and reports them as m3.

Qualifiers: u Target isotope was analyzed for but not detected above the MDC and LLD.

UI Uncertain identification for gamma spectroscopy.

X Lab-specific qualifier-please see case narrative, data summary package or contact your project manager for details.

M Reported result is less than the LLD and greater than the MDC.

TPU and Counting Uncertainty are calculated at the 95% confidence level ( 1.96-sigma).

The Qualifiers in this report are defined as follows :

M Result is < LLD and > MDC U Result is< LLD and < MDC UI Uncertain identification for gamma spectroscopy X Lab-specific qualifier-please see case narrative, data summary package or contact your project manager for details X Lab-specific qualifier-please see case narrative, data summary package or contact your project manager for details.

NI A indicates that spike recovery limits do not apply when sample concentration exceeds spike cone. by a factor of 4 or more or %RPO not applicable.

    • Indicates analyte is a surrogate/tracer compound.

/\ The Relative Percent Difference (RPO) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). ln cases where either the sample or duplicate value is less than 5X the RL , a control limit of+/- the RL is used to evaluate the DUP result.

For PS, PSD, and SOIL T results, the values listed are the measured amounts, not final concentrations.

Where the analytical method has been perfom1ed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.
