Presents a simplified model that illustrates the behavior of radiometers in steady state operation, and implications of the law of interaction between a rarefied gas and a solid surface. (MLH)

Describes an experiment that introduces students to the different types of UV rays and their effects on living things by using appropriate teaching materials and equipment. Demonstrates the effects of exposure to UV-B (fluorescent) and UV-C (germicidal) lamps by using bananas, duckweed, and the fruit fly. (Contains 14 references.) (Author/YDS)

Schools may be a significant source of radon exposure for children and staff. Describes radon detection kits and technologies, when to use them, and what action to take given the results of a radon test. (MLF)

Discusses the influence of the weather on the environmental radioactivity. Presents a method to measure the radioactivity using a Geiger counter scalar and a barometer. (JRH)

Current evidence suggests that the effects of electromagnetic fields (EMF) disturb cell homeostasis at very low intensities by influencing discrete intracellular magnetic fields. The article reviews current research about the health effects of EMF, examining historical implications, childhood studies, adult studies, and popular press reports, and…

A case of an institutionalized adult male with Down syndrome and hyperthyroidism is reported. After treatment with radioactive iodine, he was found to be markedly hypothyroid when he was reviewed 11 weeks later. Three treatment options for hyperthyroidism in Down syndrome are reviewed: surgery, medical treatments, and radiotherapy. (Author/CR)

Teaching units were developed by the Norwegian Museum of Science and Technology for visiting students. Using these units as an evaluation instrument, students' written responses were analyzed to gain insight into student understanding and attitudes toward radiation issues and to explore whether the exhibition may successfully convey scientific…

The interfacing of various spectrometers with analog output to a personal computer running Microsoft Excel in the Windows environment is described. This low cost data acquisition solution is a useful replacement of a chart recorder for various UV-visible and infrared scanning spectrophotometers.

A study of methods for protecting the special collection at the University of Abilene (Texas) from fading and deterioration caused by ultraviolet (UV) rays showed that fluorescent light filters did not correct the problem. Leaders in the preservation field say that the removal of light is the best procedure to eliminate fading. A second choice is…

Energy conservation high on the client's priority list led to a solar collector roof for the new science building at the Madeira School, located in the Virginia suburbs of Washington, D.C. (Author/MLF)

Five issues concerning nuclear power--economics, danger from accidents, environmental effects, terrorism, and alternatives are debated, with one paragraph statements from opponents and advocates on each of the topics. (CP)

Describes recent research that has made solar energy economically competitive with other energy sources. Includes solar energy building architecture, storage systems, and economic production data. (MLH)

Discusses some of the results of a grant program conducted by the American Institute of Architects Research Corporation and the Department of Housing and Urban Development. (Author/MLF)

Solar and ocean thermal energy sources offer real potential for an environmentally clean fuel by the year 2000. A review of current research contracts relating to ocean-thermal energy, cost requirements of plant construction and uses of the electricity produced, such as synthesizing ammonia and synthetic fuels, are discussed.
