AIR SAMPLES 2004 All Air Samples for the Year 2004 are within the expected historical range.
The historical range for alpha is from less than the detection limit to 0.0071 pCi/m 3 . The samples for 2004 range from less than the detection limit to. 0.0057 pCi/m 3 .
The historical range for beta is from less than the detection limit to 0.0251 pCi/m 3 . The samples for 2004 range from less than the detection limit to 0.0215 pCi/m 3 .
Air samples. are taken at various fixed locations using a line powered piston type compressor operating at a rate of i cubic foot per minute nominal. . The sample is collected on a fiberglass 2" diameter filter. Collection time is continuous with a nominal sampling period of four weeks; The air filters are analyzed for gross alpha'and gross beta using an alpha/beta proportional counter. Results are reported in picoCuries per cubic meter of air withý 2 sigma (standard deviation) value.

BIOTA 2004 "
All Biota for the Year 2004 are within the expected historical range.
The historical ranges for plant material:
Cesium-137* is less than the detection limit to 540 pCi/kg, Potassium-40** is from 2,000 to 13,000 pCi/kg, Beryllium-7*** is from less than the detection limit to 4,000 pCi/kg.
The plant sample for 2004 lies within these historical ranges. See table below.
The historical ranges for fungi:
Cesium-137 is 50 to 9,000 pCi/kg,
,Potassium-40 is from 1,000 to 12,000 pCi/kg,
-. Beryllium-7 is less than the detection limit,.
Cesium-134**** is from less than the detection limit to 45 pCi/kg.
The fungi sample for 2004 lies within these historical ranges. See table below.
Occasional sampling, most often once a year, is done on forage or wild foods as available or needed.
Samples are collected (usually 'in the Northwest quadrant) within a mile or two from the facility. These -
normally consist Of ferns (fiddleheads), edible fungi (Clavaria sp., Boleti sp., Russlae sp., grapes, etc.)-and grass. Sample sizes range from 250to 1,000 grams. The samples are weighed, placed wet in reentrant beakers and analyzed in the Gamma Spectrometer System using a reverse germanium detector. Usual spectra include primordial radionuclides, archival Cesuim-137 and occasional cosmogenic Beryllium-7.
Reporting units are picoCuries per kilogram with 2 sigma (standard deviation) value.

FISH 2004 All Fish Samples for the Year 2004 are within the expected historical range.
The historical range for Cesium-137* is from less than the detection limit to 100 pCi/kg. The samples for
- 2004 range from less than the detection limit to 20.5 pCi/kg.
The historical range for Potassium-40** is from 1,000 to 5,000 pCi/kg. The samples for 2004 range from 2,180 to 2,580 pCi/kg.
Two locations (3-4 Vernon Pond and 3-8 Route 9 Highway bridge) provide fish samples in the Spring and Fall of about one kilogram for each sample. Fish are captured via an electroshock method. The fish are frozen whole, weighed, and chopped or blended (entire) for loading into a reentrant beaker. It is subsequently analyzed with a Gamma Spectrometer System using a 'reverse germanium detector.
Radionuclides detected usually include naturally occurring Potassium-40, Thorium and Uranium with daughters, archival Cs-137 due to former open atmospheric nuclear tests, and occasional traces of cosmogenic Beryllium-7. Reporting units are picoCuries per kilogram with 2 sigma (standard deviation).

IODINE CARTRIDGES 2004 All Iodine Cartridges for the Year 2004 are within the expected historical range.
The historical range for iodine-131 in air cartridges is less than the detection limit. The samples for 2004 were less than the detection limit.
Air samples are taken at various fixed locations using a line powered piston type compressor operating at a rate of 1 cubic foot per minute nominal. The sample is collected on a charcoal cartridge loaded with TEDA for iodine collection. The charcoal cartridge follows the filtration of air by a glass fiber filter in the air sampling train at all air sampling stations. Collection time is continuous with a nominal sampling period of four weeks. Response to Chernobyl iodine release was marked, proving the sensitivity to environmental trace levels of iodine of this -system. The air cartridges are analyzed for Iodine-131 with the Gamma Spectrometer System using a reverse germanium detector. The nominal lower limit of detection is 2 x 10.5 pCi/l of air.

THERMOLUMINESCENT DOSIMETRY (TLD) DATA 2004 All TLDs for the Year 2004 ar'e'within the expected historical range.
The annual exposure at the boundary of Vermont Yankee is less than 20 1 5 mrem for 2004..
The historical range for TLDs ranges from 0 to 12.5 mR/quarter. The samples for 2004 range from 0 to 12.0 mR/quarter.
Thermoluminescent detectors are provided to the State of Vermont by Proxtronics, Inc. dnd are deployed for a quarterly sampling interval.
This method samples direct gamma'radiation in the environment. Detectors utilize crystals,.Whichstore energy from gamma and x-rays until analyzed for their cumulative energy exposure experience. Vermont has forty selected locations where direct radiation levels are measured for.
Some of these sites are loated where other types of samples are taken (e.g. air, milk, water, etc.). Le'vels of direct radiation from the natu.ral environment are routinely detected at each site. Reporting units are milliRoentgens/quarter with 2 sigma (standard deviation) value. The exposure above background; as listed below, is the exposure for each location minus the average of the exposures at the Putney Town Clerk's Office in Putney and the Vermont State Highway Garage in Wilmington.
The reporting format for TLD exposures will'change in 2005 such that the data produced by the Vermont Department of Health, and that of Vermont Yankee, can be more easily compared. Additionally, 'we anticipate some potential change in the Ireadings themselves due to our adoption of a new type of TLD, an increase in the number of Chips utilized at each station, an increase in the number of.TLD stations which will involve additional lodations, the use of a new laboratory for analysis and changes in background TLD stations. Lastly, the 2005 report will incorporate the use of a fixed background exposure rate. These changes should provide us With more accurate data, greater quality control and more readily compa'rable data:.

TRITIUM IN WATER 2004,
.VERMONT YANKEE (CONNECTICUT RIVER)
All Tritium in Water Samples for the Year 2004 are within the expected historical range.
The historical range for tritium in water is less than the detection limit. The samples for 2004 are less than the detection limit.
As part of the water sampling effort, an aliquot of the monthly grab samples is analyzed for Hydrogen-3.
Two locations are reported monthly for Hydrogen-3 content from the Connecticut River (upstream and downstream of the power station). The samples are analyzed by liquid scintillation counting. The detection limit for tritium is 0.5 nCi/l. Reporting units are nanoCuries/liter with 2 sigma (standard deviation) value.

WATER SAMPLES 2004 All Water Samples for the Year 2004 are within the expected historical range.
The historical range for alpha is from less than the detection limit to 15 pCi/1. The samples for 2004 range from less than the detection limit to 8.9 pCi/l.
The historical range for beta is from less than the detection limit to 15 pCi/l. The samples for 2004 range from less than the detection limit to 5.2 pCi/1.
Water samples are collected monthly from 8 sites. One gallon of water is placed in a reentrant beaker and analyzed on the Gamma spectrometer system Using a reverse germanium detector. Usual spectra include primordial radionuclides. Reporting units are picoCuries per liter with 2 sigma (standard deviation) value.
