The management of the risks of exposure of people to ionizing radiation is important in relation to its uses in industry and medicine, also to natural and man-made radiation in the environment. The vase majority of exposures are at a very low level of radiation dose. The risks are of inducing cancer in the exposed individuals and a smaller risk of inducing genetic damage that can be indicate that they are low. As a result, the risks are impossible to detect in population studies with any accuracy above the normal levels of cancer and genetic defects unless the dose levels are high. In practice, this means that our knowledge depends very largely on the information gained from the follow-up of the survivors of the atomic bombs dropped on Japanese cities. The risks calculated from these high-dose short-duration exposures then have to be projected down to the low-dose long-term exposures that apply generally. Recent research using cells in culture has revealed that the relationship between high- and low-dose biological damage may be much more complex than had previously been thought. The aims of this and other projects in the DOE's Low-Dose Program are to gain an understanding of the biological actions …

This report presents an overview of the Armenia-Azerbaijan conflict. This is a clash between the principles of territorial integrity and self-determination that is occurring in the Caucasus, creating the longest inter-ethnic dispute in the former Soviet Union. The report includes the background and analysis of history, warfare and peace process in the region. The report discusses the Armenian and Azerbaijani perspective, the role and views of others (Iran, Turkey, Russia), as well as the U.S. policy regarding the conflict.

Although it has been a high priority Army program, a number of factors have complicated the RAH-66 Comanche program. Since its inception, the program has been restructured several times–postponing the initial operational capability (IOC) and increasing overall program costs. Presently, there is debate within the Army regarding whether the program should be reduced significantly to make funds available to pursue other modernization priorities.

As the 108th Congress addresses short-term budget decisions, it may also want to consider the long-run impacts of those decisions and the major shifts in budget composition that are underway. Congress may be pressed to add new benefits in response to population aging, such as improved support for long-term care and broader Medicare drug coverage.

The report is categorized into seven categories: (I) Background and Analysis, (II) Budget Totals, (III) Budget Action, (IV) Outlays, (V) Receipts, (VI) Surpluses or Deficits, and (VII) The Budget and The Economy.

During the second session of the 107th Congress, the House and Senate will consider many different budgetary measures. Most of these measures will pertain to FY2003 (which will begin on October 1, 2002) and beyond, but some may make adjustments to the budget for FY2002. As the congressional session progresses, this issue brief will describe House and Senate action on major budgetary legislation within the framework of the congressional budget process and other procedural requirements.

This report discusses the issues for Congress related to fruits & vegetables. The contents include federal activities, programs, farm bill issues, & trade issues.

This document presents a groundwater monitoring plan for the 216-B-63 trench in the 200 East Area of the Hanford Site. The monitoring will be conducted in accordance with regulatory requirements specified in the Resource Conservation and Recovery Act (RCRA) of 1976. The objective of the monitoring is to determine whether any hazardous constituents are detectable in the groundwater beneath the trench. This monitoring plan will serve as the basis for demonstrating monitoring compliance at the B-63 trench under the RCRA.

A letter report issued by the General Accounting Office with an abstract that begins "The early years of the 21st century are proving to be a period of profound transition for our world, our country, and our government. The federal government needs to engage in a comprehensive review, reassessment, reprioritization, and as appropriate, re-engineering of what the government does, how it does business, and in some cases, who does the government's business. Leading public and private organizations in the United States and abroad have found that for organizations to successfully transform themselves they must often fundamentally change their culture. On September 24, 2001, GAO convened a forum to identify and discuss useful practices and lessons learned from major private and public sector organizational mergers, acquisitions, and transformations that federal agencies could implement to successfully transform their cultures and a new Department of Homeland Security could use to merge its various originating components into a unified department. The invited participants have experience managing or studying large-scale organizational mergers, acquisitions, and transformations."

This report evaluates the hazards that are unique to a compressed-natural-gas (CNG)-fueled heavy hybrid electric vehicle (HEV) design compared with a conventional heavy vehicle. The unique design features of the heavy HEV are the CNG fuel system for the internal-combustion engine (ICE) and the electric drive system. This report addresses safety issues with the CNG fuel system and the electric drive system. Vehicles on U. S. highways have been propelled by ICEs for several decades. Heavy-duty vehicles have typically been fueled by diesel fuel, and light-duty vehicles have been fueled by gasoline. The hazards and risks posed by ICE vehicles are well understood and have been generally accepted by the public. The economy, durability, and safety of ICE vehicles have established a standard for other types of vehicles. Heavy-duty (i.e., heavy) HEVs have recently been introduced to U. S. roadways, and the hazards posed by these heavy HEVs can be compared with the hazards posed by ICE vehicles. The benefits of heavy HEV technology are based on their potential for reduced fuel consumption and lower exhaust emissions, while the disadvantages are the higher acquisition cost and the expected higher maintenance costs (i.e., battery packs). The heavy HEV is more suited …

In July 2002, the U.S. Congress approved Yucca Mountain in Nevada for development as a geologic repository for spent nuclear fuel and high-level radioactive waste. This major milestone for the country's high-level radioactive waste disposal program comes after more than 20 years of scientific study and intense public interaction and outreach. The U.S. Department of Energy's (DOE) public involvement activities were driven by two federal regulations-the National Environmental Policy Act (NEPA) and the Nuclear Waste Policy Act (NWPA) of 1982, as amended. The NEPA required that DOE hold public hearings at key points in the development of an Environmental Impact Statement (EIS) and the NWPA required the agency to conduct public hearings in the vicinity of the site prior to making a recommendation regarding the site's suitability. The NWPA also provided a roadmap for how DOE would interact with affected units of government, which include the state of Nevada and the counties surrounding the site. As the Project moves into the next phase--applying for a license to construct a repository-the challenge of public interaction and outreach remains. It has become increasingly important to provide tools to communicate to the public the importance of the Yucca Mountain Project. Sharing the science …

In July 2002, the U.S. Congress approved Yucca Mountain in Nevada as the nation's first long-term geologic repository site for spent nuclear fuel and high-level radioactive waste. This major milestone for the country's high-level radioactive waste disposal program comes after more than twenty years of scientific study and intense public interaction and outreach. This paper describes public interaction and outreach challenges faced by the U.S. Department of Energy's (DOE) Yucca Mountain Project in the past and what additional communication strategies may be instituted following the July 2002 approval by the U.S. Congress to develop the site as the nation's first long-term geologic repository for spent nuclear fuel and high-level radioactive waste. The DOE public involvement activities were driven by two federal regulations--the National Environmental Policy Act (NEPA) and the Nuclear Waste Policy Act (NWPA) of 1982, as amended. The NEPA required that DOE hold public hearings at key points in the development of an Environmental Impact Statement (EIS) and the NWPA required the agency to conduct public hearings in the vicinity of the site prior to making a recommendation regarding the site's suitability. The NWPA also provided a roadmap for how DOE would interact with affected units of government, which …

Proposals to replace all or part of the income tax and proposals for national health care have sparked congressional interest in possible sources of additional revenue. A value-added tax (VAT) or a national sales tax (NST) have been frequently discussed as possible new tax sources. Both the VAT and the NST are taxes on the consumption of goods and services and are conceptually similar. Yet, these taxes also have significant differences. This issue brief discusses some of the potential policy implications associated with these differences.

This report addresses the current policy on immigration visa issuances and options for reassigning this function to the proposed Department of Homeland Security (DHS). It opens with an overview of visa issuances, with sections on procedures for aliens coming to live in the United States permanently and on procedures for aliens admitted for temporary stays. An analysis of the grounds for excluding aliens follows. The report summarizes the debate on transferring visa issuance policy functions to homeland security and concludes with a discussion of the legislative proposals to reassign the visa issuance activities and to revise visa issuance policies.

This report summarizes a preliminary study aimed at estimating the potential of saving potable water, (and the electrical energy used to heat it), that is presently lost directly to the drain while occupants wait for hot water to arrive at the faucet (point of use). Data were collected from five single-family homes in Palo Alto, California. Despite the small sample size in this study, the results make a compelling case for retrofitting homes with hot water recirculation systems to eliminate unnecessary wastage of water at the point of use. Technical as well as behavioral and attitudinal changes towards water conservation are necessary for a fulfilling and successful conservation effort. This report focuses on the technical issues, but behavioral issues are also noted, which may be factored into future studies involving local and state governments and utility companies.
