Proposes the use of problems of the everyday world to motivate students to master basic physical principles. Cites the example of conversion of solar energy by a photovoltaic cell as a source of topics in electricity and solid state physics. (CP)

Discusses an engineering conference at which participants agreed that solar energy is a feasible energy source, although costs of such technology are presently very high. Also describes recent developments in solar energy research, and estimates the costs of this technology. (MLH)

Describes the steps in writing a computer program to solve radioactive decay problems by a digital method. (CP)

Attempts to utilize nonpolluting solar energy for home heating and electrical power are examined. (DE)

Drawing on testimony presented at hearings before the Subcommittee on Health and Safety of the House of Representatives conducted between February 28 and June 12, 1984, this staff report addresses the general topic of video display terminals (VDTs) and possible health hazards in the workplace. An introduction presents the history of the…

Nuclear winter, a term used to describe potential long-term climate and environmental effects of nuclear war, has been a subject of debate and controversy. This report examines and presents scientific and policy implications of nuclear winter. Contents include: (1) an executive summary (highlighting previous and current studies on the topic); (2)…

The environment we live in today is filled with human-created electromagnetic fields generated by a variety of sources, including radio and television transmitters, power lines, and visual display terminals. (In addition, there exists a natural background of electromagnetic fields.) The term "electromagnetic pollution" is often used to…

By far, the greatest risk to health from radon occurs when the gas enters the house from underlying soil and is inhaled. The U.S. Environmental Protection Agency (EPA) is studying ways to reduce radon in houses, including methods to remove the gas from water to prevent its release in houses when the water is used. While this research has not…

Almost from the introduction of the new technology into newsrooms, the video display terminal (VDT) has raised health concerns. Ironically, the newspaper industry--which ordinarily would be at the forefront, acting as a watchdog over worker health and safety concerns--has initiated little news coverage of the VDT radiation issue. The Newspaper…

Solar retrofits are devices of structures designed to be attached to existing buildings to augment their existing heating sources with solar energy. An investigation of how solar retrofits should be designed to suit the climate and resources of Arkansas is the subject of this report. Following an introduction (section 1), section 2 focuses on…

Discusses an experiment on determination of vegetative radioactivity resulting from nuclear tests. Included is a detailed description of experimental procedures. (CC)

Many scientists feel that research into nuclear safety has been diverted or distorted, and the results of the research concealed or inaccurately reported on a large number of occasions. Of particular concern have been the emergency cooling systems which have not, as yet, been adequately tested. (Author/MA)

This publication contains descriptions of the winning entries to the National Science Teachers Association (NSTA) Teacher Participation Contest conducted in 1976. This was a nationwide contest for the design of activities around energy themes at any grade level, K-12. The ten winning entries described here are: (1) Energy Units for Primary Grades;…

This book is a compendium of educational materials of interest to individuals involved in diagnostic radiologic technology. The book is divided into twelve sections. Each part corresponds to a subject area included in the curriculum guide for the American Society of Radiologic Technologists. Each section is subdivided into sections entitled:…

The purpose of this report is to present and prioritize the major environmental, safety, and social/institutional issues associated with the further development of Solar Total Energy Systems (STES). Solar total energy systems represent a specific application of the Federally-funded solar technologies. To provide a background for this analysis, the…
