Reviews the principal sources of natural and man-made radiation, current representative levels of radiation exposure in our daily lives, and possible harmful effects of this exposure. (MLH)

Discusses the application of the laws of physics to natural phenomena, including Jackrabbit ears, transparent atmosphere, formation of ice, and long-wave radiation. (YP)

Food irradiation has been studied for years, but now with new Food and Drug Administration (FDA) approval of low-dose radiation, it may become a popular method to retard food spoilage. Radiolytic products, feeding studies, and nuclear issues are among the areas addressed. (JN)

Discusses potential war time and medical uses for chemical compounds giving protection against radiation damage. Describes compounds known to protect, research aimed at discovering such compounds, and problems of toxicity. (EB)

Film has been used to detect x-rays since the early days of their discovery by Rontgen. Although nowadays superseded by other techniques, film still provides a cheap means of x-ray detection, making it attractive in high-school or undergraduate university courses. If some sort of quantitative result is required, the film's optical absorbance or…

Introduction: Innovative technology has led to high-precision radiation therapy that has dramatically altered the practice of radiation oncology. This qualitative study explored the implementation of this innovation into practice from the perspective of the practitioners in a large academic radiation medicine program and aimed to improve…

The measurement of solar UV under water is not a simple process. In the underwater environment the difficulty of obtaining useable data is greatly amplified due to the optically complicated and at times unpredictable nature of water itself. The following practical exercise designed for use in the Year 11 and Year 12 Physics classroom aims to…

This training manual consists of two parts. The first covers general information and outlines various applications of food irradiation technology. The second section details laboratory exercises used to demonstrate the principles of radiation processing and the effects of radiation treatment on certain types of food. The chapters outline…

This article briefly discusses some of the dangers involved in the use of radioisotopes and includes a comprehensive list of precautions and laboratory rules for use during radiobiology experiments. (Author)

The text takes a practical approach to the understanding of industrial radiation hazards. It is intended for the layman who requires a basic understanding of the relationship of radiation problems to his own field. Discussion includes such topics as: uses which benefit mankind; radiation energy versus fission energy; effects of excessive radiation…

"Nuclear Winter" was recently coined to describe the climatic and biological effects of a nuclear war. These effects are discussed based on models, simulations, scenarios, and projections. Effects on human populations are also considered. (JN)

Declares that media sensationalism and the ignoring of facts has contributed to both public and scientific overreaction to radiation hazards. Examples of public concern and lack of scientific evidence are given. (PR)
