RAI Regarding OOL-01-06 Email Youngblood to Carson dated March 19, 2007 Comment: I have a question about the sample data in survey unit OOL-01-06 that I did not "see" to ask about before. The survey unit has one sample at 2.68 SOF and the sampling was done on a 25-square meter systematic grid. Could you share the SOF data for each of the radionuclides of concern in this survey unit.
I ask because if the activity is predominantly Co-60, which has an area factor = 1.8 for the grid size, then have you exceeded the DCGL-EMC? I see that you used the WRS test for evaluating the entire data set, but did that address all the questions about sample number OOL-01-06-010-F- SD?
Yankee Response:
The table below provides the activity and the fraction of the DCGL for each of the four radionuclides used in the elevated measurement calculation:
Nuclide Activity (pCi/g) DCGL(pCi/g) Fraction of DCGLw Co-60 1.29 1.6 0.80 Cs-137 1.31 3.4 0.38 Sr-90 0.90 0.7 1.28 C-14 0.54 2.2 0.25 Total SOF 1 2.71 The differences in the SOF above and the SOF in the FSS report (2.68) can be attributed to the number of significant figures used in determining the SOF.
The equation used for calculating thef(DCGLEMc) is:
C, +/- C2 Cn DCGLý x (AreaFactor 1) DCGL2 x (AreaFactor2) DCGL, x (AreaFactor,)
Plugging in the values from the table above for the concentration and the 10 mrem/yr DCGLs and using the radionuclide-specific area factors for 25 n'? from LTP Appendix 6Q:
1.29 1.31 0.90 0.54
+ + + =0.57 1.6xl.8 3.4x 3.7 0.7x54 2.2x860 Other radionuclides were identified above the Critical Level but were below the MDA, therefore contributing very little to the overall fraction. As can be seen by the above values, Sr-90 was the predominant radionuclide.
