Book Description
An argon gas forced transpiration arc (FTA) source used to produce a high intensity 180 nm to above 2.5 micron continuous spectrum was described. Calibration technics, monitoring instrumentation and procedures for studying the effects of ultraviolet on the eye were presented. An ultraviolet space energy profile was composed using data from rocket flights. (Author).

Book Description
The adverse effects of sunlight on the skin are well known, but only now is the scientific basis and rationale for treatment being evaluated. With the current level of interest from the general public and dermatologists in suntanning, sunburn and skin cancer, there is a great need for an authoritative, comprehensive review of the mechanisms, prevention and treatment of photodamage. There are only a handful of reputable clinical investigators who could put together an important volume and of this group, Dr. Gilchrest is probably the leading worker. She has collected all the latest information on photobiology, the effect of light on skin structure and function, clinical problems, prevention in adults and children, and medical and surgical treatment

Book Description
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 Description
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 Description
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).
