Imaging of artwork is an important aspect of art conservation, technical art history, and art authentication. Many forms of near-infrared (NIR) imaging are used by conservators, archaeologists, forensic scientists, and technical art historians to examine the underdrawings of paintings, to detect damages and restorations, to enhance faded or…

The advent of the global information society and a myriad of other rapidly changing variables are presenting many new and unique challenges for the twenty-first century workforce, and perhaps the most pressing of these challenges is actually meeting the needs for qualified workers to fill the positions in emerging and growing fields. One such…

Described are lay-ideas which may exist about ionizing radiation, the importance of these ideas for risk management, and the relationships between various lay-ideas. Lay-ideas were used to gain a better insight into the problems of learning about ionizing radiation and to construct appropriate teaching materials and strategies. (KR)

CCD spectrometers available at Stockholm House of Science allow students to measure the radiation from the Sun. Students are fascinated by the information that can be gathered from the spectrum, including the temperature of the solar surface and the presence of certain elements in both the Sun's atmosphere and the Earth's.

Describes the Solar Energy Research Institute (SERI) its growth, mission, and projected future role. (SL)

The SunSmart Schools Accreditation Programme (SSAP) was launched as a national programme in October 2005 to help reduce the risk of excessive child exposure to ultraviolet radiation. As part of the need for evaluation, this paper reports the findings of a national survey of a randomly selected sample of approximately 12% of New Zealand primary…

Few scientific issues arouse as much public controversy as the effects of radiation. This booklet is an attempt to summarize what is known about radiation and provide a basis for further discussion and debate. The first four chapters of the booklet are based on the most recent reports to the United Nations' General Assembly by the United Nations…

This publication contains statewide standards for the radiologic technology program in Georgia. The standards are divided into 12 categories; Foundations (philosophy, purpose, goals, program objectives, availability, evaluation); Admissions (admission requirements, provisional admission requirements, recruitment, evaluation and planning); Program…

Electricity is an increasingly important part of our everyday lives. Its versatility allows one to heat, cool, and light homes; cook meals; watch television; listen to music; power computers; make medical diagnosis and treatment; explore the vastness of space; and study the tiniest molecules. Nuclear energy, second to coal, surpasses natural gas,…

Nuclear physics fundamentals are presented in this sixth unit of the Project Physics text for use by senior high students. Included are discussions of radioactivity, taking into account Bacquerel's discovery, radioactive elements, properties of radiations, radioactive transformations, decay series, and half-lives. Isotopes are analyzed in…

Topic 7, Atomic Bombs and Radiation, from a theme issue on Teaching World History Through Science Fiction, stimulates discussion on mutation and radiation effects. (JB)

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)
