Evaluation of the radionuclide concentrations in soil and plants from the 1975 terrestrial survey of Bikini and Eneu Islands

Description: In June 1975 a radiological survey was conducted of the terrestrial environment of Bikini and Eneu islands (Bikini Atoll) to evaluate the potential radiation dose to the returning Bikini population. In this report, we present measurements of the radionuclide concentration in soil profiles and in dominant species of edible and nonedible, indicator plants. The use of these data to derive relationships to predict the plant uptake of radionuclides from soil is described. Approximately 620 soil and … more

Response of Shortgrass Plains Vegetation to Chronic and Seasonally Administered Gamma Radiation

Description: In order to determine the effect of radiation on the structure of native shortgrass plains vegetation, an 8750 Ci 137Cs source was installed on the Central Plains Experimental Range near Nunn, Colorado; The experimental area was divided into 6 treatment sectors, a control, 2 sectors for chronic exposure (irradiation initiated April 1969 and continuing as of August 1971), and one each for spring, summer and late fall seasonal semi-acute (30 day), exposures which were administered during April, J… more

Remeasurement of permanent vegetation plots in the Great Smoky Mountains National Park, Tennessee, USA, and the implications of climatic changes on vegetation. Environmental Sciences Division publication No. 1111

Description: This report summarizes field work over two summers (1976 and 1977) to relocate, monument and reinventory permanent vegetation plots in the Great Smoky Mountains National Park. These plots were first established by the senior author and R.H. Whittaker in 1959-62. The inventory results are discussed in terms of vegetation changes in high-altitudinal forest ecosystems, in particular the spruce-fir forests, and the factors, climate shift and biotic and abiotic agents, bringing about vegetation chan… more

Ferruginous Hawks and Geothermal Development. Annual Report

Description: The effects on nesting ferruginous hawks of impact treatments was studied. These treatments were undertaken as follows: 3 nests were visited on foot; 3 were visited by vehicle; 3 were disturbed by discharging firearms; and 2 were disturbed by placing continuously operating engines near them. Data recorded include the general behavior of adults, their presence or absence, time of visit, and conspicuous environmental conditions. Nest failures and young per attempted nesting are given and compared… more

Functional complexity and ecosystem stability: an experimental approach

Description: The complexity-stability hypothesis was experimentally tested using intact terrestrial microcosms. Functional complexity was defined as the number and significance of component interactions (i.e., population interactions, physical-chemical reactions, biological turnover rates) influenced by nonlinearities, feedbacks, and time delays. It was postulated that functional complexity could be nondestructively measured through analysis of a signal generated from the system. Power spectral analysis of … more

Cesium-137 in deer: Savannah River Plant vs. southeastern coastal plain herds

Description: The /sup 137/Cs content in deer killed during programmed hunts at the Savannah River Plant (SRP) has averaged 9.0 pCi/g. This value, based on measurements of 13,907 deer taken over 14 years (1965 to 1978), similar to the value obtained for 552 deer from other southeastern Coastal Plain locations, indicating the /sup 137/Cs content is due to fallout from the atmospheric testing of nuclear weapons rather than from SRP operations. The computerized SRP data base for each harvested deer includes age… more

Soils of the Pacific Northwest shrub-steppe. Occurrence and properties of soils on the Arid Land Ecology Reserve, Hanford Reservation

Description: The soils of the Arid Land Ecology Reserve, encompassing the IBP Grassland Biome intensive study site on the ERDA Hanford Reservation, are representative of a larger geographical region including much of the Columbia Plateau and Pacific Northwest shrub-steppe. This results from a unique diversity in parent materials of mixed origin derived from the loess eolian, lacustrine and stream-laid material including glacial outwashes, river terraces, flood plains and alluvial fans and meteorological fac… more

Gamma-ray spectral determinations with a portable analyzer

Description: A portable sodium iodide spectrometer was used in a variety of field applications. The spectrometer is a battery-operated system complete with a 5 x 5 cm NaI(Tl) detector, 1024 channel memory divisible into four quadrants, special summation and calibration circuits, and a telemeter output for data transmittals.

Evaluation of oxidation techniques for preparing bioassay and environmental samples for liquid scintillation counting

Description: In environmental and biological monitoring for carbon-14 and tritium, the presence of color and chemical quenching agents in the samples can degrade the efficiency of liquid scintillation counting. A series of experiments was performed to evaluate the usefulness, under routine conditions, of first oxidizing the samples to improve the counting by removing the color and quenching agents. The scintillation counter was calibrated for the effects of quenching agents on its counting efficiency. Oxidi… more
