Environmental radiological assessments rely heavily on the use of mathematical models. The predictions of these models are inherently uncertain because these models are inexact representations of real systems. The major sources of this uncertainty are related to biases in model formulation and...

To compensate for the potential for overly conservative estimates of risk using standard US Environmental Protection Agency methods, an uncertainty analysis should be performed as an integral part of each risk assessment. Uncertainty analyses allow one to obtain quantitative results in the form...

This study determines the extent to which it is possible to develop monetary estimates of the marginal social cost of fuels, using natural gas to test a methodology that could be applied to other fuels. This requires review of previous estimates of both market and nonmarket costs to the extent...

This report provides background information for the Bonneville Power Administration (Bonneville) in its efforts to quantify the environmental externalities associated with new electricity resources. A more detailed companion document has been provided to Bonneville for internal use. This report...

Analysis of the radiological health effects of nuclear power plant accidents requires models for predicting early health effects, cancers and benign thyroid nodules, and genetic effects. Since the publication of the Reactor Safety Study, additional information on radiological health effects has...

The Title I groundwater standards for inactive uranium mill tailings sites, which were promulgated on January 5, 1983, by the US Environmental Protection Agency (EPA) for the Uranium Mill Tailings Remedial Action (UMTRA) Project, were remanded to the EPA on September 3, 1985, by the US Tenth...

Through June, 1978, one major emphasis of the program is a regional coal assessment for input to the ERDA National Coal Assessment (NCA). The NCA will utilize information on regional energy options to (1) generate development scenarios and to (2) evaluate regional impacts associated with these...

The purpose of the Programmatic Risk Management System (PRMS) is to evaluate and manage potential risks associated with proposed projects (i.e., new products or processes, or possible research and technological development projects). Although the PRMS considers some technical aspects of risk,...

This areport explores the implications of an index-of-harm methodology that compares occupational risks among workers exposed to radiological and nonradiological harms. It extends the work of the International Commission on Radiological Protection (ICRP) by considering American rather than...
