EXECUTIVE SUMMARY

None of the radionuclides detected in samples collected during the third 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 third 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, July 1 through September 30, 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:

Analysis

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. No statistical differences were observed between Distant locations than Boundary locations for either gross alpha or gross beta concentrations measured during any week of the third quarter. 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. 

 

Charcoal Cartridge

Iodine-131

Iodine-131 was not reported on any charcoal cartridge batches during any week of the quarter.

Atmospheric Moisture

Liquid

Tritium

A total of 19 samples were collected.  Seventeen of these samples had tritium results greater than the 3s uncertainty. No sample result exceeded the DCG for tritium in air. Results were consistent with historical measurements.

Precipitation

Liquid

Tritium

Six results for samples collected were available.  Two of the results were greater than the 3s uncertainty.  The concentrations were consistent with those reported across the region by the Environmental Protection Agency and with previous results.

Milk

Liquid

Iodine-131, gamma-emitting radionuclides

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

Grain

Vegetation

Gamma-emitting radionuclides, 90Sr

Fourteen wheat samples were collected.  No manmade gamma-emitting radionuclides were found in any sample.  Strontium-90 was detected in six samples at levels consistent with historical results.

Large Game Animals

Tissue

Gamma-emitting radionuclides

Three large game animals (all pronghorn) were sampled. No man-made radionuclides were detected in animal tissues.
