6.  Summary and conclusions

Statistical analyses of Boundary and Distant gross alpha and beta air concentrations collected with low volume air samplers indicated that the INEEL did not increase radionuclide concentrations above background at Boundary and Distant locations. Radionuclides measured in third quarter, 2001, in ESER samples could not be directly linked with INEEL activities.  Levels of detected radionuclides were below regulatory limits and were not different from values measured at other locations across the United States.  Based on these results, it is the conclusion of the ESER Program that the INEEL did not measurably contribute to offsite radionuclide concentrations of constituents sampled during the third quarter of 2001.
