In a recent article in "Physics Today," Meredith and Redish emphasized the need to make introductory physics courses beneficial for life sciences majors. In this study, a lab activity is proposed to measure the intensity of electromagnetic waves emitted by cell phones and connect these measurements to various standards, biological…

If we abide by the familiar saying "you are what you eat," it is understandable that people may be concerned with the incredible advances in food science technology and their possible impacts on human health. For example, in recent years high-tech scientific processes such as genetic modification, irradiation, and cloning have all been used to…

Describes some basic findings in the radiation chemistry of genetic material derived from studies of model systems. Uses these findings to extrapolate the consequences of radiation damage to DNA within cells. (CS)

Discusses the effects of radiation on dividing cells and factors influencing these effects; also briefly reviews the radical mechanism for radiation damage. Emphasizes the importance of oxygen in radiation effects. (CS)

Discusses various aspects of radiation damage to biological material, including free radical mechanisms, radiation sensitization and protection, tumor hypoxia, mechanism of hypoxic cell radiosensitization, redox model for radiation modification, sensitizer probes of cellular radiation targets, pulse radiolysis studies of free radical kinetics,…

Describes a class activity, a game called "Beware--Radiation," developed as a framework for the introduction of the topic of radiation. Reports that both students and teachers had similar and mostly wrong preconceptions. (Author/YP)

Cites reasons why Penicillium claviforme is an exceptionally good species for ultraviolet induced mutation experiments. Provides a set of laboratory instructions for teachers and students. Includes a discussion section. (ML)

This manual was prepared for a training program in Nuclear Medicine Technology at the University of Cincinnati. Instructional materials for students enrolled in these courses in the training program include: Nuclear Physics and Instrumentation, Radionuclide Measurements, Radiation Protection, and Tracer Methodology and Radiopharmaceuticals.
