Recent advances in the development of radionuclide labeled monoclonal antibodies as radiopharmaceuticals should result in commercially available products in the near future. This presentation describes mechanisms by which radiation can destroy cells, factors influencing the potential for successful treatment, concepts to understanding the use of…

Describes a technique for extracting a radioactive source from the atmosphere using a balloon, as a strategy to generate students' enthusiasm for and understanding of radioactivity experiments. (JRH)

Discusses four keyboarding hazards that are technique related: carpal tunnel syndrome, eyestrain, fatigue, and radiation exposure. Includes technique suggestions and a plan for limiting the amount of time behind a video display terminal. (JOW)

Attempts to clear up misunderstandings about radon and outlines information teachers can convey to their students. Includes a brief history of radon, health threats posed by radon, methods to measure radon quantities, homeowner risks and preventative actions, and a glossary of radon terms. (MDH)

Contends that storytelling is a device which physics teachers can add to their repertoire for motivating and encouraging students. Presents an example of effective storytelling using the story of the COBE discovery of ripples in cosmic background radiation. (Author/WRM)

Documents a quasi-scientific comparative study of two groups of 'recent school leavers' in the UK. Studies non-science university undergraduates and explores whether people living with the immediacy and relevance of higher-than-average levels of radioactivity were more knowledgeable and emotionally detached than a similar group removed from this…

Traditionally nuclear chemistry appears in the last few chapters of chemistry textbooks and is not normally considered a mainstream topic. In addition, some science teachers lack the training or equipment to teach nuclear chemistry. Yet nuclear chemistry is a very important topic that should be taught in all chemistry classrooms. Learning about…

People usually talk about "hot and cold" colours without really thinking of the impact these definitions may have on scientific understanding. These colours are associated with the human sensations of hot and cold, and this idea is consistent with commonsense and daily experience. Interacting with students, we detect conceptual conflicts when they…

Describes a technique in which blackbody radiation emitted or absorbed by a single microwave cavity mode is detected and displayed on an oscilloscope. (Author/CP)

Describes the nuclear fuel cycle and the environmental and social problems which might result from United States or world dependence on nuclear power. (This is a continuation of SE 514 938.) (LS)

Photographs of snow covered buildings are used to illustrate thermal radiation from various types of structures and the effect of insulation on heat loss. (CP)

The new Terraset Elementary School in Reston, Virginia, uses earth as a cover for the roof area and for about 80 percent of the wall area. A heat recovery system will be used with solar collectors playing a primary role in heating and cooling. (Author/MLF)

Describes an experiment in which the beam of X-rays is simulated through the use of a laser as a monochromatic light source and the crystal is replaced by photographically prepared masks. A strong diffraction pattern as large as 20 cm. can be obtained. (GS)

Discusses minimum necessary nuclear fundamentals of radioactive isotopes such as levels of activity, specific activity and the use of carrier materials. Corrections that need to be taken into account in using an isotope to obtain a valid result are also described and statistics for a valid result are included. (BR)

Describes screening systems for environmental mutagens, characteristics of the ideal screening system, characteristics of currently employed screening systems, correlative information required for decision making, and application of data to human populations. (GS)
