Following the rapid developments in the UV-B measurement techniques and the rapidly growing research in the field in the late 80's and early 90's, we organized a large gathering of distinguished experts in a NATO Advanced Study Institute, held in Halkidiki, Greece on October, 2-11. 1995. The Institute was organized so as to include state of the art lectures on most aspects of solar ultraviolet radiation and its effects. This was achieved by extended lectures and discussions given in five sessions by 27 lecturers and a demonstration of filed measurements and calibration techniques at the end of the Institute. The ASI began with the sun and fundamentals on solar radiative emissions and their variability in time and continued with the interaction of solar Ultraviolet with the atmosphere through the complex scattering processes and photochemical reactions involved. Particular emphasis was given to changes in atmospheric composition imposed by different manifestations of the solar activity cycle. as well as on the modelling of radiative transfer through the atmosphere and the ocean under variable environmental conditions. Overviews on the ozone issue. its monitoring and variability were extensively discussed with emphasis on the observed acceleration of ozone decline in the early 90's. This acceleration had as a consequence, significant increases in UV-B radiation observed at a few world-wide distributed stations.

The inspiration for this monograph derived from the realization that human technical capacity has become so great that we can, even without malice, substantially modify and damage the gigantic and remote outer limit of our planet, the stratosphere. Above the atmosphere of our ordinary experience, the stratosphere is a tenuous layer of gas, blocked from rapid exchange with the troposphere, some twenty kilometers above the surface of the earth, seldom reached by humans, and yet a fragile shell which shields life on earth from a band of solar radiation of demonstrable injurious potential. It is immediately obvious that if stratospheric ozone were reduced and consequently the intensity of solar ultraviolet radiation reaching the earth's surface were increased, then human skin cancer, known to be related to solar ultraviolet exposure, would also be increased. But how does one even begin to estimate the impact of changed solar ultraviolet radiation on such a diverse. interacting, and complex ecosystem as the oceans? Studies which I conducted in Iceland focused on this question and were noted to the Marine Sciences Panel of the Scientific Affairs Committee of NATO by Professor Unnsteinn Stefansson, leading to a request to investigate the possibility of organizing a NATO sponsored Advanced Research Institute on this topic.

This textbook provides a comprehensive understanding of the scattered and filtered solar UV environment, the techniques to measure this radiation and the resulting UV exposures to humans. As is well known, the incidence of skin cancer and sun-related eye disorders can be reduced by minimization exposure to UV radiation. The book aims to quantify, understand and provide information on the effects of filtered and scattered UV light.

An excellent summary of solar UV measurement for anyone involved in, or contemplating, measuring the UV part of the solar spectrum. The book is addressed predominantly to the newcomer to this expanding area of environmental measurement, but contains sufficient detail and practical information to be a valuable reference for the more experienced worker. The practical considerations of solar UV measurement are clearly described and the book explores the current state of the art of UV monitoring, explained by the historical demand for data. The many applications of solar UV data are discussed and the importance of making appropriate measurements and collecting sufficient supporting data for the analysis required of these applications is highlighted.

Gafchromic external beam therapy (EBT) films have been widely used in clinical dosimetric applications due to their high sensitivity to ionizing radiation such as X-ray and electron beams. In 2011, International Specialty Products (ISP) introduced a new generation of films called EBT3 film. The films exhibit color changes from light green to darker color with the increment of absorbed doses of ionizing radiation. The color changes of the films are commonly characterized using flatbed reflective scanner, and subsequently being used to predict the absorbed dose. Besides ionizing radiation, EBT3 films have also been proven to have high sensitivity towards ultraviolet radiation, and hence, make it a promising method in measuring solar ultraviolet radiation exposure. This research book presents a comprehensive visible spectroscopy method in characterizing the color changes of EBT3 films specifically for the measurement of solar ultraviolet exposure. The visible spectroscopy method and analysis presented in this book is also applicable for other types of transparent films for radiation dosimetry.

Although variations in the intensity of solar ultraviolet irradiation of the Earth's surface may provide significant opportunities for observation in the ultraviolet spectrum, research in the ultraviolet region has been neglected by terrestrial scientists. The spectral properties of vegetation and soils and of undisturbed weathered natural surfaces of rocks and sediments, in situ, are unknown. Limited spectrophotometric data obtained in the laboratory, but of samples removed from their environment, indicate that there may be less distinctive spectral character in the ultraviolet than at the longer wavelengths. Spectral reconnaissance studies in the near-ultraviolet region are therefore warranted.

This publication originates from the NATO Advanced Study Institute on Environmental Radiation: Impact on Ecosystems and Human Health and Predictive Models, held in Pisa, Italy, in June 2001. The book offers not only basic information on the action mechanisms of UV radiation on ecosystems and various biological systems, but also a picture of the possible scenarios of the long-term global increase of environmental UV radiation, with emphasis on the research aspects aimed at the proper quantitative assessment of risk factors and the formulation of reliable predictive models. The purpose of the authors is to present a critical discussion on how changes in UV radiation will affect ecosystems and the biological processes needed to sustain life on Earth and to provide useful hints for future actions of governmental and international agencies, as well as non-governmental organizations. The book is structured in four sections: the first one is devoted to a general overview of the consequences of ozone depletion and to the basic concepts of radiation measurements and monitoring; the other three sections are devoted to the effects on plants, aquatic ecosystems and human health.
