Solar energy, heat recovery, energy-saving design, and a unique cafeteria/theater are some of the features at the award-winning Tri-County Vocational-Technical Regional High School in Franklin, Massachusetts. (MLF)

Reviews the long term implications of photosynthesis as a source of solar energy and food. (SL)

Reviews research which has found variations in the decay rate for various types of radioactive decay. (SL)

Discusses the impact of radioactive waste management system on social and political development. The article also presents (1) types of information necessary to estimate the costs and consequences of radioactive waste management; and (2) an index of radioactive hazards to improve the basis for policy decisions. (HM)

Through a course in energy conservation and domestic solar energy technology, students evaluated the thermal performance of existing campus structures and made suggestions for improvements in thermal efficiency. Besides making some of these improvements, the students also designed, built, and operated a solar greenhouse. (MA)

Presents basic theory of silicon solar cells and discusses their use in experiments in undergraduate teaching laboratories. (SL)

Described is how to build a solar furnace model. A detailed list of materials and methods are included along with diagrams. This particular activity is part of an audiotutorial unit concerned with the energy crisis and energy alternatives. (MA)

A high school class, housed in a temporary prefabricated structure, designed and built a solar energy element to heat the building. (JD)

Solar energy collector panels are used as a freestanding canopy over walks that will connect an arts complex eventually consisting of five buildings. (Author/MLF)

Evaluates how well the media guided readers and viewers through the Chernobyl disaster. Concludes that the press and television did not provide enough radiation and risk information in their coverage of the Chernobyl accident, but what was provided was appropriate, even-handed, and conservative. (NKA)

Described are the natural trace radionuclides in ground water. Indicates the geologic origin of these radionuclides. Discusses the importance of these radionuclides. Suggests future uses of a number of additional radionuclides. (CW)

Buildings can be designed in harmony with the natural environment, and new techniques of "active" solar design exist to collect and use solar energy for space heating and cooling. Preservation and reuse of existing buildings and neighborhoods are other ways to conserve energy. (Author/MLF)

Speaks to the role of vocational education in providing massive training programs to prepare technicians and other service personnel to perform installation and service functions necessary to support architects and engineers designing and developing solar energy systems. (HD)

Discusses solar thermal collectors, solar thermal electric power conversion, photovoltaic power conversion, and wind energy conversion, and discusses implications for industrial arts. (TA)

Outlines the discovery and nature of ultraviolet light, discusses some applications for these wavelengths, and describes a number of experiments with ultraviolet radiation suitable for secondary school science classes. (JR)
