UV-B (Ultraviolet B), is electromagnetic radiation light from the sun, with a medium wave which is mostly absorbed by the ozone layer. The biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules.
This book describes the basics of UV-B - how it is reaching the earth’s surface, its impact on the environment’s biotic components, and its impact on human biological systems. Previously, “UV-B” has been perceived as purely negative for the environment. However, with recent advancements in techniques, UV-B research has taken a dramatic U-turn. This change in mindset has altered the perception of UV-B and research is now focusing on how it is beneficial for humans. This book is a comprehensive look at the state-of-the-art of UV-B research, covering past to present advancements which have not yet been compiled in any comprehensive book written on the subject. It focuses on UV-B as an emerging technology, and examines its role in human welfare. The first two chapters give a description of introductory UV-B and its climatology. UV-B radiation interacting with living systems has some specific cellular targets and consequently evocates negative responses, which have been discussed together with possible mechanism s of action in later chapters. Plants try to acclimatize themselves in changing environment and evolve some acclimation responses that have been discussed in some chapters.
Researchers and students will learn more about trends in UV-B research. Pharma industries will be interested in this book from health and food products point of views.
