Measuring The Visible

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.

The Museum Environment, Second Edition deals with the behavior and conservation of the various classes of museum exhibit. This book is divided into six sections that provide museum specifications for conservation. This text highlights the three contributing factors in the deterioration and decay of museum exhibits, namely light, humidity, and air pollution. Each section describes the mechanism of deterioration and the appropriate “preventive conservation . The changes in this edition from the previous include the electronic hygrometry, fluorescent lamps, buffered cases, air conditioning systems, and data logging and control in historic buildings. This book is of great value to conservation researchers and museum workers.

Beyond the Visible: A handbook of best practice in plant UV photobiology presents methods for research on the responses of plants to ultraviolet (UV) radiation. The knowledge needed to make informed decisions about manipulation and quantification of UV radiation is summarized. Practical recommendations for obtaining reliable and relevant data and interpretations are given. The handbook covers research both on terrestrial and aquatic plants and it deals with experimentation on ecological, eco-physiological and physiological questions. The handbook includes 115 figures, mostly in colour, 19 tables and 12 text boxes. It is the result of the activities of COST action FA0906 "UV4growth", and it includes contributions by 17 authors. From the foreword by Dr. Marcel A. K. Jansen: This book ... is an important contribution towards such sound experimental design, promoting both "good practice" in UV-B manipulation, as well as "standardisation" of methodologies. Writing an authoritative book that will steer experimental approaches over the coming years, can not easily be done by an individual, but rather requires the concerted effort of a team of expert scientists. ... This is surely an excellent example of a concerted, Europeanwide activity that will boost the plant UV-B research field in Europe and beyond, for years to come.
