This booklet is one of the booklets in the "Understanding the Atom Series" published by the U. S. Atomic Energy Commission for high school science teachers and their students. The instruments used to detect both particles and electromagnetic radiation that emerge from the nucleus are described. The counters reviewed include ionization chambers,…

This report presents a plan developed by the Energy Research and Development Administration (ERDA) concerning future energy sources. The plan summarizes ERDA's current views on the energy technologies the U.S. will need to achieve long-term energy independence. The role of the private sector in the development and commercialization of new energy…

Results and conclusions to date of a program to design, erect, and test a 5,000-square-foot solar energy system are presented in this report. The program described demonstrates the ability of solar collectors to supplement the heating and hot water requirements of North View Junior High School in suburban Minneapolis. The report discusses in…

Reports on the results of a survey of the attitudes of rural fifth through seventh grade students toward the energy crisis. Among results, it was found that children at this age level appeared to understand some of the problems and implications of electricity generation from fossil and nuclear fuels, and that overall, older children and females…

The design and effectiveness of a number of government/industry active solar demonstration projects. (Author/MLF)

This purpose of this article is to explain, in simple terms, the difficulty students have in a British sixthform course in proceeding from X-ray photograph to molecular structure. (HM)

Presents an undergraduate physical chemistry laboratory experiment describing the measurement of the proton magnetic resonance spectra. (HM)

Shows that when positions annihilate in solid materials the energy distribution of the annihilation gamma rays is much broader than that of a 0.511-Mev gamma peak. This broadening is caused by the momentum distribution of the electrons in the material. (Author/GA)

Experiments to measure range, range straggling, stopping power, and energy straggling of alpha particles are discussed in this article. Commercially available equipment with simple modifications is used for these measurements. (Author/GA)

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)
