Preface

In the name of Allah, the Most Beneficent, the Most Merciful. I am very thankful to Allah Almighty for giving me the ability, the capabilities, the resources, and the courage to complete this task.

Medical and Health Physics is a broad and one of the fast-growing fields around the world, based on the safe use of radiation. The enormous benefits of radiation used in diagnostic, therapeutic, and healthcare applications have made researchers further explore this field. Because of its interdisciplinary nature, medical and health physics is open to researchers, investigators, and educators from many basic and applied fields. The entire area of medical and health physics is based on radiation and its proper uses. Radiation is a blessing due to its revolutionary pros, benefits, and use in many fields. In this regard, I and my friends and collaborators published the book ‘An Introduction to Medical Physics’, a few years ago. With the great popularity of the book around the globe and the demand from students, friends, and colleagues, I feel that it would be very important to move forward and publish more in this area. After looking at the requirements and demands in medical and health physics, radiation sciences, and applied electromagnetic waves, I decided to write another book in this series with the title ‘An Introduction to Nonionizing Radiation.’ Relatively little known about nonionizing radiation and very little published material in this area, I decided to write on the fundamental concepts, characteristic properties, uses, benefits, and especially the harms and hazards associated with nonionizing radiation. The frequent use of lasers, mobile phones, antennas, infrared radiation, visible light, and ultraviolet radiation compelled me to write about and report the latest findings on the harms and hazards associated with the use of nonionizing radiation with their beneficial applications. Thus, this book provides a brief understanding of the fundamental concepts of nonionizing radiation. The book talks about how nonionizing radiation can be used to serve and help people. The book also discusses the nature and strength of harms and hazards one can get from nonionizing radiation exposure. At the same time, this book also talks about how safety and protection from the adverse effects of nonionizing radiation can be attained during its beneficial use by following proper rules, regulations, and guidelines.

In completing this task, I am very thankful to all authors who contributed valuable ideas to flourish the beauty and depth of the subject matter discussed in this book.

I am very thankful to Humaira Hashmi and the Bentham Books publisher, who helped and cooperated to achieve this astonishing goal.
