  • This book was born from our combined years exploring the use of optically stimulated luminescence (OSL) in different areas of radiation dosimetry with a seemingly unending curiosity about the physics of the process and our aspirations and dreams concerning potential applications. We wished to learn about and understand the challenges presented by the many different areas of dosimetry and how OSL could play a useful role and, of course, we hoped that we would make meaningful contributions to the field.

  • According to classical physics the particle cannot be a wave, and the wave cannot be a particle. However, Einstein, while explaining the photoelectric effect (PEE), postulated that electromagnetic radiation has a dual wave-particle nature. He used the term photon to refer to the particle of electromagnetic radiation. He proposed a simple equation to relate the energy of the photon E to the frequency n and wavelength l of electromagnetic wave.

  • The aim of this volume is threefold. It is intended, firstly, as a revision aid for students on Masters level degree courses in Radiation Science. These will already have received lectures at various levels of detail on most of the topics covered here. Experience has shown, however, that in preparing for examinations, especially oral examinations, students benefit from an opportunity to put details in the context of the whole. This I have tried to do by drawing attention to important connections that exist between topics treated in different chapters.

  • The textbook written by Paul Davies in 19891 entitled, The New Physics, commenced with the following opinion. Many elderly scientists look back nostalgically at the first 30 years of the 20th century, and refer to it as the golden age of physics. Historians, however, may come to regard those years as the dawning of the New Physics. The events which the quantum and relativity theories set in train are only now impinging on science, and many physicists believe that the golden age was only the beginning of the revolution....

  • Brachytherapy Brachytherapy is the direct implantation of radioactive sources into the prostate. It is based on the principle that the deposition of radiation energy in tissues decreases as a function of the square of the distance from the source (Chap. 81). The goal is to deliver intensive irradiation to the prostate, minimizing the exposure of the surrounding tissues. The current standard technique achieves a more homogeneous dose distribution by placing seeds according to a customized template based on CT and ultrasonographic assessment of the tumor and computer-optimized dosimetry.

  • Radiation Marrow aplasia is a major acute sequela of radiation. Radiation damages DNA; tissues dependent on active mitosis are particularly susceptible. Nuclear accidents can involve not only power plant workers but also employees of hospitals, laboratories, and industry (food sterilization, metal radiography, etc.), as well as innocents exposed to stolen, misplaced, or misused sources.

  • Positron emission tomography (PET), a powerful research tool 20 years ago, has recently gained widespread application in oncology and is now a procedure clinically available on each continent. Despite the fact only a few PET centers are dedicated to children, data from Children’s Oncology Group indicate that virtually all children in North America have easy access to a PET center. As the table of contents of this book indicates, clinical and research applications of PET for children with cancer represent only a fraction of the current pediatric uses for PET technology.
