Indoor concentrations of radon 222 and its daughters: sources, range, and environmental influences

Description: The author here reviews what is presently known about factors affecting indoor concentrations of radon 222 and its daughters. In US single-family homes, radon concentrations are found to average about 1.5 pCi/1, but substantially higher concentrations occur frequently: perhaps a million US homes have concentrations exceeding 8 pCi/1 (from which occupants receive radiation doses comparable to those now experienced by uranium miners). The major contributor to indoor radon is ordinary soil underly… more

Migration of radionuclides following shallow land burial

Description: A study of radionuclide migration was conducted at a facility used from 1944 to 1949 for the shallow land burial of radwaste produced during operations with two reactors and related nuclear research. It is situated in glacial drift 45 m thick. Underlying the drift is a generally level Silurian dolomite bedrock 60 m thick. The thickness of the drift decreases as the surface slopes downhill (north) until the dolomite reaches the surface and forms the bed of a river, 700 m to the north. This study… more

Spatial patterns of radiological dose from wells drilled near nuclear waste repositories

Description: This report describes methodology for assessing the spatial patterns of radiological dose to man from wells drilled near nuclear waste repositories. Descriptions of the various categories of water wells and a model of a typical aquifer are presented. The equation governing the one-dimensional flow of waste in groundwater through porous media to a well is discussed. This is followed by development of a method for constructing lines of constant dose from a well located randomly in the plane of th… more

Bedded-salt repository analysis. Final report

Description: This report contains a description of an analysis of generic nuclear waste repository in bedded salt. This analysis was performed by TASC for inclusion in a major Lawrence Livermore Laboratory report to NRC; this report therefore should be viewed as providing more complete and detailed information about this analysis than was possible to include in the LLL report. The analysis is performed with the NUTRAN computer codes which are described in the report. The model to be analyzed is defined, and… more

Preparation of a computer-compatible data base on an operating total energy system. Final report. [Indian Creek Village, Overland Park, Johnson Co. , Kansas]

Description: This report documents the development of a computerized data base on the long-term performance of the Indian Creek Total Energy System, and it is intended to be a user's manual for the data base and the accompanying energy-balance computer program. The data base may be used as a standard of comparison for the performance predicted by energy-system-simulation software. The TES became operational in 1972 to meet the projected electrical, space conditioning, and domestic hot water needs for t… more

Environmental monitoring final report: groundwater chemical analyses

Description: This report presents the results of analyses of groundwater qualtiy at the SRC-I Demonstration Plant site in Newman, Kentucky. Samples were obtained from a network of 23 groundwater observation wells installed during previous studies. The groundwater was well within US EPA Interim Primary Drinking Water Standards for trace metals, radioactivity, and pesticides, but exceeded the standard for coliform bacteria. Several US EPA Secondary Drinking Water Standards were exceeded, namely, manganese, co… more

Water quality in the vicinity of Fenton Hill, 1985 and 1986: Progress report

Description: Water quality data have been collected since 1974 from established surface and groundwater stations at and in the vicinity of Fenton Hill (Hot Dry Rock Geothermal Demonstration Site) located in the Jemez Mountains. This is part of a continuing program of environmental studies. Data on chemical quality of water were determined for samples collected from 13 surface water and 19 groundwater stations in 1985 and 1986. There were slight variations in the chemical quality of the ground and surface wa… more

Defluoridation study for Boise geothermal water

Description: Methods of removing fluorides from water are reviewed and recommendations are made for treating geothermal water used by the Boise Geothermal Project, Boise, Idaho. The Boise geothermal water except for its high fluoride content would be high quality, suitable for primary drinking water. Fluoride ranges from about 15 to 25 mg/l in water from various wells in the Boise region where the Project plans to obtain hot water. Four techniques for removing fluorides from water have been studied extensiv… more

Characterizing the sources, range, and environmental influences of radon 222 and its decay products

Description: Recent results from our group directly assist efforts to identify and control excessive concentrations of radon 222 and its decay products in residential environments. We have demonstrated directly the importance of pressure-induced flow of soil gas for transport of radon from the ground into houses. Analysis of available information from measurements of concentration in US homes has resulted in a quantitative appreciation of the distribution of indoor levels, including the degree of dependence… more

Radionuclide deposition and exposure in the Federal Republic of Germany after the Chernobyl accident

Description: Analyses of air, water, and foodstuff samples, together with in situ gamma spectrometric measurements in the Federal Republic of Germany, have documented the deposition and exposure consequences of the Chernobyl accident. In some cases, exposure values are significantly higher than background levels. Data compiled for the period from the initial identification of excess atmospheric radioactivity to the present, represent a unique resource for testing and validating models of environmental trans… more

Health effects workshop summary. [Carcinogenic and mutagenic effects of chlorination of water supplies]

Description: Cancer is a very serious health problem in the United States and a large fraction of human cancer is of environmental origin. The epidemiological data are presented that suggest that some part of environmental cancer is due to substances present in chlorinated water supplies. A number of compounds which are carcinogenic in animal model studies are known to be in chlorinated water supplies. So cancer has been identified as a real and not just potential problem in the chlorination of water suppli… more

Investigation of the effects of halogenated organic compounds produced in cooling systems and process effluents on aquatic organisms

Description: Both public health and environmental concern have been generated by the identification of an assemblage of halogenated organic compounds produced in the chlorination of drinking water, sewage, and power plant cooling waters. Our objectives were to determine which compounds contributed significantly to the toxicity of such chloro-organic mixtures and whether significant interaction occurred. Toxicity studies were conducted using the embryo of the carp (Cyprinus carpio) and the cladoceran Daphnia… more

Geochemistry of water in relation to cardiovascular disease

Description: Relations between trace and major element chemistry of drinking water and cardiovascular diseases are reviewed and documented. Several aspects of the problem, related both to the pathway that drinking water takes to man and to its transit through man, are reviewed. Several steps in the pathogenesis of cardiovascular disease that could be affected by water factors were explored. There is little evidence bearing on the contribution from drinking water to human tissue levels of cadmium, chromium, … more
