Methodology for performing measurements to release material from radiological control
This report describes the existing and proposed methodologies for performing measurements of contamination prior to releasing material for uncontrolled use at the Hanford Site. The technical basis for the proposed methodology, a modification to the existing contamination survey protocol, is also described. The modified methodology, which includes a large-area swipe followed by a statistical survey, can be used to survey material that is unlikely to be contaminated for release to controlled and uncontrolled areas. The material evaluation procedure that is used to determine the likelihood of contamination is also described.

A study of overproduction and enhanced secretion of enzymes. Quarterly report
Wood decay within forests, a significant renewable photosynthetic energy resource, is caused primarily by Basidiomycetous fungi, e.g., white rot fungi. These organisms possess the ability to degrade lignin, cellulose and hemicellulose, the main organic polymers of wood. In the case of the white rot fungi, e.g., Coriolus versicolor, the capacity results from the fungus` ability to elaborate extracellular cellulolytic and ligninolytic enzymes. With regard to the latter, at least one of the enzymes, polyphenol oxidase (PPO) appears within a defined growth medium. This proposal focuses on the over-production and enhanced secretion of PPO, cellulase and lignin peroxidase. There are two major sections to the proposal: (1) overproduction of lignocellulolytic enzymes by genetic engineering methodologies and hyper-production and enhanced secretion of these enzymes by biochemical/electro microscopical techniques and (2) the biochemical/electron microscopical method involves substrate induction and the time-dependent addition of respiration and PPO enzymes.

Laser power beaming for satellite applications
A serious consideration of laser power beaming for satellite applications appears to have grown out of a NASA mission analysis for transmitting power to lunar bases during the two week dark period. System analyses showed that laser power beaming to the moon in conjunction with efficient, large area solar cell collection panels, were an attractive alternative to other schemes such as battery storage and nuclear generators, largely because of the high space transportation costs. The primary difficulty with this scheme is the need for very high average power visible lasers. One system study indicated that lasers in excess of 10 MW at a wavelength of approximately 850 nm were required. Although such lasers systems have received much attention for military applications, their realization is still a long term goal.

A technology to analyze spatiotemporal landscape dynamics: Application to Cadiz Township (Wisconsin)
As landscape ecology has matured, it has gone beyond description of land-use changes, to examining the functional relationships between spatial patterns of landscapes and ecological processes. Attempts to describe these relationships at larger scales or in complex landscapes have been hampered by the lack of spatially explicit distributed parameter models linked dynamically to geographical information systems (GIS). This paper describes developments we have made to link such models to GIS and to develop visualization methods (a graphical interface) that permits the user to readily manipulate large element files containing model parameters. We then present preliminary results illustrating the effects of pattern (in an agricultural landscape) on water and material flow across a heterogeneous landscape composed of multiple watersheds. These dynamics are driven in large measure by the location, size, and number of forest patches. By use of soil, hydrologic, and vegetation data from a real landscape, the effects of spatial relocation of vegetation on water and sediment dynamics are explored through the model-GIS combination. The spatiotemporal modeling approach described here could be useful in effectively managing ecosystem restoration and rehabilitation at the landscape scale.

Bioavailability of sediment-bound contaminants to marine organisms
The bioavailability of sediment-bound contaminants to marine organisms indicates that there exists a potential for transfer of these contaminants through marine food webs to commercial fisheries products consumed by humans. However, there has been relatively little effort to combine and synthesize data on chemical/biological interactions between benthic animals and seagrasses and the sediments in which they reside on the one hand, and on the chemistry of bioaccumulation on the other. This report provides a conceptual basis for an approach to bioavailability and biomagnification of sediment-bound contaminants that reviews biological and chemical approaches.

Fresh Kills leachate treatment and minimization study: Volume 2, Modeling, monitoring and evaluation. Final report
The New York City Department of Sanitation is developing a comprehensive landfill leachate management plan for the Fresh Kills landfill, located on the western shore of Staten Island, New York. The 3000-acre facility, owned and operated by the City of New York, has been developed into four distinct mounds that correspond to areas designated as Sections 1/9, 2/8, 3/4 and 6/7. In developing a comprehensive leachate management plan, the estimating leachate flow rates is important in designing appropriate treatment alternatives to reduce the offsite migration that pollutes both surface water and groundwater resources.Estimating the leachate flow rates from Sections 1/9 and 6/7 was given priority using an available model, hydrologic evaluation of landfill performance (HELP), and a new model, flow investigation for landfill leachate (FILL). The field-scale analysis for leachate flow included data collection of the leachate mound-level from piezometers and monitoring wells installed on-site, for six months period. From the leachate mound-head contours and flow-gradients, Leachate flow rates were computed using Darcy`s Law.

Cancer increase study methodology: A review and discussion of the ``Southeastern Massachusetts Health Study 1978--1986``
In October 1990 the Massachusetts Department of Public Health released a report of an epidemiologic study of adult leukemia occurring in the vicinity of the Pilgrim 1 Nuclear Power Plant near Plymouth, Massachusetts. The study used a case-control design in which adult leukemia cases occurring between 1978 and 1986 in 22 towns were compared with persons without leukemia (controls) selected from the same study population. Exposure scores, used to estimate potential for exposure to radioactive emissions from Pilgrim, were calculated for all cases and controls. When the exposure scores of cases were compared with those of controls, the analyses showed the scores to be higher for the leukemia cases, suggesting that individuals with the highest potential for exposure to Pilgrim emissions had a significantly increased risk of leukemia. This association was found only for cases diagnosed before 1984; for cases diagnosed during 1984, 1985, or 1986, no association was observed between leukemia case status and potential for exposure to emissions from the plant. Our review of the report and supporting documents shows no major methodologic problems that would account for the finding of an association between leukemia risk and the Pilgrim plant. Examination of the study findings in relation to …

Analysis of the application of decontamination technologies to radioactive metal waste minimization using expert systems
Radioactive metal waste makes up a significant portion of the waste currently being sent for disposal. Recovery of this metal as a valuable resource is possible through the use of decontamination technologies. Through the development and use of expert systems a comparison can be made of laser decontamination, a technology currently under development at Ames Laboratory, with currently available decontamination technologies for applicability to the types of metal waste being generated and the effectiveness of these versus simply disposing of the waste. These technologies can be technically and economically evaluated by the use of expert systems techniques to provide a waste management decision making tool that generates, given an identified metal waste, waste management recommendations. The user enters waste characteristic information as input and the system then recommends decontamination technologies, determines residual contamination levels and possible waste management strategies, carries out a cost analysis and then ranks, according to cost, the possibilities for management of the waste. The expert system was developed using information from literature and personnel experienced in the use of decontamination technologies and requires validation by human experts and assignment of confidence factors to the knowledge represented within.
