Download or read book UV-A written by John Parrish and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin of this text was a request by industry and government to summarize the biological effects and to estimate the limits of safe exposure to longwave ul traviolet radiation. The specific issue was the safety of a small medium-pressure mercury arc designed to emit UV-A (NUVA-Lite, L. D. Caulk Co. , Milford, Delaware) for photopolymerization of resinous fillings used in dentistry. How- ever, the context grew to become a consideration of the risks and benefits to hu mans of electromagnetic radiation between the biologically active short UV and the visible spectrum. We have accumulated data from our own experimental work and from the literature and have attempted to put this information in the perspective of known biologic effects of ultraviolet radiation as it influences hu mans. Interest in the biological effects of longwave ultraviolet radiation is increas ing in all of the many scientific disciplines that make up the complex field of photobiology. In order to minimize the chance for error and personal prejudice and to maximize the use of expertise, each chapter has been reviewed by several authorities. Some of the contributions of this group led to significant alterations and creative additions to the chapter, and these persons deserve not only our sin cere gratitude but also recognition by the reader. These include Chapters 2 and 3: Dr. Robert E. Levin, Mr. Charles P. Comeau, Mr. Donald Gonser, Dr. David Sliney; Chapter 5: Dr. Jerry Williams, Dr. Robert Webb, Dr. Madhu A.
Book Synopsis Radiotherapy of Intraocular and Orbital Tumors by : Winfried E. Alberti
Download or read book Radiotherapy of Intraocular and Orbital Tumors written by Winfried E. Alberti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiotherapy of Intraocular and Orbital Tumors presents a new approach to the role of radiation therapy in the management of ophthalmic cancer. The indications for ultrasonography, computed tomography, and magnetic resonance imaging studies are analyzed, and treatment techniques, together with their results, are described for each tumor. Particle beam and plaque irradiation are reviewed, and conservative and surgical management of radiation effects are detailed. In the past, most books on this subject included a chapter on radiotherapy but emphasized the dangers of radiation complications. However, great progress in understanding the effects of irradiation upon the tissues of the eye and orbit, new therapeutic equipment, and new imaging techniques (CT, MRI) allow for careful treatment planning. This book has taken the long overdue step of reconsidering the role of irradiation of the eye so that it may take its place as a respected, rather than feared, treatment in the combined modality approach so important today. Together with experts in relevant fields, the editors have produced a refreshingly clear and thoroughly referenced volume which will be a valuable asset to all ophthalmologists, radiation oncologists, pediatricians, endocrinologists, oncologists, and residents in training, as well as to students in these disciplines.

Book Synopsis Challenges in Sun Protection by : Christian Surber
Download or read book Challenges in Sun Protection written by Christian Surber and published by Karger Medical and Scientific Publishers. This book was released on 2021-10-25 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 20th century, tanned skin was associated with good health. However, people began to protect themselves against potential overexposure to avoid sunburns. Around 1945, the first sunscreen products became available. In the years to follow, a vast number of different sunscreen filters and frameworks regulating filter substances and preparations, and methods characterizing sunscreen products were developed. The perception regarding the tasks of sunscreen products changed several times – initially it was promoted as a lifestyle product, then as a skin cancer preventive means, and more recently also for anti-aging. Different purposes and the widespread use of these products have led to myriad studies and a wealth of information. In this volume, the editors present a current collection of information analyzing and discussing issues related to sunscreen products and their use. These include challenges regarding the ideal sunscreen product including filter selection and formulation issues, measurement methods, performance characterization, safety, and regulatory issues. Further papers address topics related to the use of sunscreen products in everyday life, in vulnerable cohorts and outdoor workers. Controversial topics such as environmental effects of sunscreen products and the risks and benefits of UV radiation in the context of skin cancer, vitamin D and cardiovascular and metabolic health are also covered.
Book Synopsis Skin Cancer and UV Radiation by : Peter Altmeyer
Download or read book Skin Cancer and UV Radiation written by Peter Altmeyer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1476 pages. Available in PDF, EPUB and Kindle. Book excerpt: UV radiation is recognized as the major risk factor for skin can cer. For the last three decades the incidence and mortality of skin cancer have been increasing steadily in almost all parts of the world. Unfortunately, there have been very few advances in the management and treatment of skin cancer. In comparison to other malignant tumors, skin cancer offers the unique opportuni ty to identify this tumor at an early stage. Thus, there is strong interest in preventing death by early diagnosis and prompt treat ment. The proceedings of the International Congress on Skin Cancer and UV Radiation which was held in Bochum Germany in October 1996, reflect the newest scientific standards in the field of skin cancer. The conference in Bochum was a platform for leading scientists from all over the world to discuss the complexity and diversity of UV radiation in its interaction with the skin. Starting with basic science like physiology, immunology, and molecular biochemistry of the skin as influenced by UV radiati on, the book presents a profound survey into the field of skin can cer by focusing on the latest scientific results in prevention, early detection, treatment, and epidemiology. The congress in Bochum in 1996 was organized to provide a starting point for coordinated European strategies against skin cancer with internationally renown scientists.

Book Synopsis A Comparative Study of the Effects of Ultraviolet Radiation on the Eye by : Donald G. Pitts
Download or read book A Comparative Study of the Effects of Ultraviolet Radiation on the Eye written by Donald G. Pitts and published by . This book was released on 1970 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fluid transpiration arc (FTA) filled with argon gas was used to produce a high intensity continuous spectrum. Animal and human exposures were made to establish the photokeratitis threshold and abiotic action spectrum. The abiotic action spectrum ranged from 210 to 320 nm. The peak of the ultraviolet threshold curve was at 270 nm for the rabbit and the primate. The rabbit photokeratitis threshold was 0.05 X 10 to the 6th power ergs/sq cm at 270 nm. The primate threshold was 0.04 X 10 to the 4th power ergs/sq cm at 270 nm. The human threshold at 280 nm was 0.05 X 10 to the 6th power ergs/sq cm. Formulas and calculations are given for protection against ultraviolet encountered in the space environment. (Author).
Book Synopsis Transmission of the Ocular Media by : Edward A. Boettner
Download or read book Transmission of the Ocular Media written by Edward A. Boettner and published by . This book was released on 1962 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spectral transmittance of ultraviolet, visible, and near infrared light through the ocular media of humans has been measured. Using freshly enucleated eyes, the transmittances of each component part (cornea, aqueous humor, lens, vitreous humor) were determined for the wavelength range from 0.22 to 2.8 microns. To date 9 eyes have been measured, ranging in age from 4 weeks to 75 years. Two types of measurements were made: the first to measure the total light transmitted (direct and scattered) at each wavelength and the second to measure the percent transmittance of that light passing directly through the various media without absorption or scattering. The results show that: (a) the transmission of ultraviolet radiation decreases with the age of the eye; (b) the transmission of infrared radiation appears to be independent of the age; and (c) the maximum total transmittance of the whole eye, about 81 percent, is obtained in the region from 600 to 850 millimicrons.
