None of the radionuclides detected in samples collected during the first quarter of 2010 could be directly linked with INL Site activities. Levels of detected radionuclides were no different than values measured at other locations across the United States or were consistent with levels measured historically at the INL Site. All detected radionuclide concentrations were well below guidelines set by the U.S. Department of Energy (DOE) and regulatory standards established by the U.S. Environmental Protection Agency (EPA) for protection of the public. |
This report for the first quarter of 2010 contains results from the Environmental Surveillance, Education and Research (ESER) Program’s monitoring of the Department of Energy’s Idaho National Laboratory (INL) Site’s offsite environment, January 1 through March 31, 2010. All sample types (media) and the sampling schedule followed during 2010 are listed in Appendix A. Specifically, this report contains the results for the following:

Results |
|
Air |
Filters |
Gross alpha, gross beta |
No statistical differences were noted in either gross alpha or gross beta data on quarterly and monthly comparisons. Gross beta concentrations were statistically higher at Distant locations than Boundary locations during one week in January but the data appeared normal. No result exceeded the DCG for gross alpha or gross beta activity in air. |

Gamma-emitting radionuclides, select actinides (241Am, 238Pu, and 239,240 Pu), 90Sr |
No man-made radionuclides were detected. Actinide data were not yet availabe |
|
|
Charcoal Cartridge |
Iodine-131 |
No detections of 131I were made during the first quarter. |
|
Atmospheric Moisture |
Liquid |
Tritium |
A total of 11 samples were collected. Five of these samples had tritium results greater than the 3s uncertainty. No sample result exceeded the DCG for tritium in air. |
|
Precipitation |
Liquid |
Tritium |
Ten samples were collected. Four of the results were greater than the 3s uncertainty. The concentration was consistent with those reported across the region by the Environmental Protection Agency and with previous results. |

Iodine-131, gamma-emitting radionuclides |
Twenty-nine samples, including two duplicates, were collected. No Iodine-131 or other manmade gamma-emitting radionuclides were detected in any sample. |

Large Game Animals |
Tissue |
Gamma-emitting radionuclides |
No large game animals were available for sampling in the first quarter. |

Waterfowl |
Tissue |
Gamma-emitting radionuclides |
At special request, a dead Canada Goose was collected near the Radioactive Waste Management Complex. No manmade gamma-emitting radionuclides were detected in any goose tissues.. |
