FINAL DATA REPORT Characterization of Drain Piping In-Place 4th Floor and B-25 Boxes 3638-003 and 3638-005 201 Varick Street, New York City, New York July 2022 ATTACHMENT G DATA VERIFICATION - RADIOLOGICAL CONSTITUENTS Instrument and ambient site background were determined for field measurements based on exploratory data analysis performed on site data. Field data were divided into data sets according to associated 4th Floor Riser pipe segments (Risers 64, 76, 128, 144, 145), remaining 4th Floor piping, and other. Other data included measurements on the 11 unlabeled pipe segments and 12 pipe segments not associated with a specific 4th Floor Riser. Each data set was further divided by measurement type; beta/gamma static, removable alpha, and removable beta.
Each data set was evaluated using exploratory data analysis including calculation of summary statistics, graphical representation of the data set (box plots, histograms, normal probability plots) to visually identify potential outliers, and calculation of background threshold limits (BTVs). BTVs are upper bounds for background distributions such that values exceeding the BTV provide evidence of data exceeding background. BTVs were calculated as the 95% Upper Simultaneous Limit for normally distributed data, or the 95% Chebyshev Upper Prediction Limit for data sets that did not follow a specific distribution (i.e., nonparametric data).
Beta/gamma static data sets followed normal or approximate normal distributions with no outliers. All seven beta/gamma static data sets have similar average results and range of results.
All beta/gamma static measurements were identified as not exceeding background. The beta/gamma results are summarized in Table G-1.
Removable alpha data sets did not follow a known distribution. Alpha counts are primarily zero or one and are more closely associated with binomial distributions or step functions. The maximum removable alpha count (pipe segment 46-2, 4th Floor Riser 145) represents a potential outlier and was identified as exceeding background. The removable alpha results are summarized in Table G-2.
Removable beta data sets followed normal or approximate normal distributions with no outliers.
All seven removable beta data sets have similar average results and range of results. All removable beta measurements were identified as not exceeding background. The removable beta results are summarized in Table G-3.
Laboratory analytical results were evaluated against instrument background by the laboratory.
All results receiving a U flag were identified as not exceeding background. The laboratory results are provided in Attachment D.
