“…Levels of 13' %s are sporadically measured in deer muscle. Levels of 139Cs in background deer samples collected from Stevens County were higher than levels in Hanford deer because of historic patterns of fallout weapons testing (Poston and Cooper 1995). 137Cs accumulates in testes at level commeasurable with the liver.…”

“…Strontium-90 was measured routinely in deer bone and antler samples (Tiller et al 1996;Poston and Cooper 1995). Although recent results show favorable agreement in %Sr concentrations between affected and normal deer (Table 3.10), results for Sr in bone dating back to 1990 show considerably higher concentrations in some Hanford deer bones comrade to the 1995 values.…”

“…Liver is the organ of choice as it would accumulate the highest levels of ingested plutonium. The apparent iack of any positive measurement of plutonium in jackrabbit or deer liver (Poston and Cooper 1995) suggests that environmental exposure to plutonium at Hanford is minimal, and consequently, the likelihood of an elevated dose from plutonium affecting testicular development in deer is very remote.…”

Executive SummaryRocky Mountain mule deer (Odocoileus hemionus hemionus), common residents of the Hanford Site, are an important part of the shrub-steppe ecosystem as well as being valued for aesthetics and hunting. Because mule deer have been protected from hunting on the Site for 50 years, the herd has developed unique population characteristics, including a large number of old animals and males with either large or atypically developed antlers, in contrast to other herds in the semi-arid regions of the Northwest.Hanford Site mule deer have been studied since 1991 because of the herd's unique nature and high degree of public interest. A special study of the mule deer herd was initiated in 1993 after observations were made of a relatively large number of male deer with atypical, velvet-covered antlers. This report specifically describes our analyses of adult male deer found on the Site with atypical antlers. The report includes estimates of population densities and composition; home ranges, habitat uses, and dietary habits; natural and human-induced causes of mortality; and the herd's overall health and reproductive status.Examinations of adult male deer exhibiting unusually shaped, velvet-covered antlers were found to have permanently infertile, atrophied (shrunken as opposed to incompletely developed) testicles. The frequency of affected deer observed on Hanford was highly correlated to the frequency of older-aged animals found onsite and was difficult to compare with other more heavily hunted populations. Morphologic, physiologic, and clinical and pathological results showed essentially normal findings, but indicated the causative agent(s) act directly on testicular tissues. Figure S.1 shows a logistical flow diagram for potential causative factors responsible for deer exhibiting unusuaIly shaped, velvet-covered antlers. Radiation, natural aging, infectious agents, and genetic factors were ruled out as primary potential causes. Other factors ruled out as likely causative agents that could warrant further field investigations were thermal stress, nutritional stress, plant estrogens, heavy metals, and herbicides/ pesticides/insectides (Hanford and/or adjacent agricultural areas). Essentially no data were gathered to examine plant or fungal toxins, which could be causative agents.Population-level results indicated that the Hanford Site herd contained a relatively large proportion of male deer, primarily as a result of the lack of hunting pressure and mild winters. Fawn production on Hanford was low. Deer were most abundant along the Columbia River (approximately 330 animals) and on the western portions of the FitznerEberhardt Arid Lands Ecology (ALE) Reserve and were lowest on the 200 Area plateau to the southern border and the eastern portions of ALE. Deer diets and movements indicated a high dependency on riverine habitat, sagebrush, and the sand dunes habitat. The data also sh...

SummaryEnvironmental monitoring is conducted on the U.S. Department of Energy (DOE) Hanford Site to comply with DOE Orders and federal and state regulations. Major objectives of the monitoring are to characterize contaminant levels in the environment and to determine site contributions to the contaminant inventory. This report focuses on surface soil and perennial vegetation samples collected between 1971 and 2008 as part of the Pacific Northwest National Laboratory Surface Environmental Surveillance Project performed under contract to DOE. Areas sampled under this program are located on the Hanford Site but outside facility boundaries and on public lands surrounding the Hanford Site. Additional samples were collected during the past 8 years under DOE projects that evaluated parcels of land for radiological release. These data were included because the same sampling methodology and analytical laboratory were used for the projects.The spatial and temporal trends of six radionuclides collected over a 38-year period were evaluated. The radionuclides-cobalt-60, cesium-137, strontium-90, plutonium-238, plutonium-239/240, and uranium (reported as either uranium-238 or total uranium)-were selected because they persist in the environment and are still being monitored routinely and reported in Hanford Site environmental reports. All these radionuclides were associated with plutonium production and waste management of activities occurring on the site. Other sources include fallout from atmospheric testing of nuclear weapons, which ended in 1980, and the Chernobyl explosion in 1986. Uranium is also a natural component of the soil.Spatial trends involved comparing data from onsite locations with data from offsite locations. Offsite locations were divided into three categories based on distance from the site. These distance categories were perimeter (which included sites that were on the Hanford Site but away from facilities and reactors, such as sites on Rattlesnake Mountain (i.e., Fitzner/Eberhardt Arid Lands Ecology Reserve) and across the Columbia River); nearby locations (sample sites within 20 miles of the closest site boundary); and distant sites (locations greater than 20 miles from the closest site boundary).Additional spatial analysis evaluated data collected from the various onsite operational areas. Onsite areas included• the 100 Areas where the reactors were located along the Columbia River• 200 Areas on the Central Plateau and the site of much of the fuel reprocessing and waste storage• 300 Area on the southern edge of the site near the Columbia River where fuel fabrication and testing occurred• the 400 Area, which was the site of the Fast Flux Test Facility (FFTF)• the 600 Area, which included open areas between the other industrialized areas, such as the Hanford town site, near the Energy Northwest plant, and FFTF; and two perimeter locations at the Prosser and Yakima barricades.For temporal analysis, data were compared across decades (1970s, 1980s, 1990s, and 2000s).Soil and vegetation concentrations of radi...
