Notes:
L
Selected results are discussed in the appropriate sections of the text of this report.
2. "NO" . means the parameter was. not detected. Detection limits are available in the
Paducah OREIS database.
3. Monitoring programs often include measurement of extremely low concentrations of
radionuclides, below the detection limit of the counting instruments. Less-than-detectable data
. will produce numerical measurements with values below the detection limit and sometimes
negative values. All of the actUal values, including those that are negative, are included in the
statistical analyses in accordance with DOE's Environmental Regulatory Guide for
Radiological Effluent Monitoring and Environmental Surveillance (DOE 1991).
. -
4. Average values are calculated using the actual result. values from the OREIS database,
including when results are below the detection level. Where actual result values below the
detection level are not available, the detection level is used in the calculations. Therefore,
average values reported where any results used were below detection levels are actually lower
than reported. ..
