Heavily ionizing charged particles produce radiation damage tracks in a wide variety of insulating materials. The experimental properties of these tracks and track recorders are described. The mechanisms by which the tracks are produced are discussed. (Author/KR)

Stefan's law is demonstrated by measuring the temperature of the tungsten filament of an electric light bulb and plotting a log-log graph of temperature against power dissipation. (MLH)

Children's ideas about radiation and radioactivity are reviewed and several common areas of misunderstanding are identified. An approach to teaching the topic at the secondary school level which seeks to specifically address known difficulties is outlined. (CW)

Proposes the use of problems of the everyday world to motivate students to master basic physical principles. Cites the example of conversion of solar energy by a photovoltaic cell as a source of topics in electricity and solid state physics. (CP)

Describes the steps in writing a computer program to solve radioactive decay problems by a digital method. (CP)

Described are the characteristics of the laser and its effects on the body. Discussed are examples of laser treatments, including angioplasty, ophthalmology, and dermatology. A discussion of lasers of clinical interest and their applications is presented. (YP)

Discussed are technological advances applying computer techniques for image acquisition and processing, including digital radiography, computed tomography, and nuclear magnetic resonance imaging. Several diagrams and pictures showing the use of each technique are presented. (YP)

Discussed is a radionuclide imaging technique, including the gamma camera, image analysis computer, radiopharmaceuticals, and positron emission tomography. Several pictures showing the use of this technique are presented. (YP)

Described is the role of the medical physicist in five areas of medical application, including radiotherapy, nuclear medicine, diagnostic radiology, environmental radioactivity, and dosimetry and personal monitoring. The management contribution of the medical physicist is discussed. Provided are two examples of new techniques influencing radiation…

Concentrates on describing the implementation of the hardware systems based on the BBC microcomputer. Describes the electronic systems used to amplify the signals from the detector and to convert the signal to digital format. Discusses the software that must be used and the system performance. (CW)
