    The third in a three-volume set exploring Problems and Solutions in Medical Physics, this volume explores common questions and their solutions in Radiotherapy. This invaluable study guide should be used in conjunction with other key textbooks in the field to provide additional learning opportunities. One hundred and forty-four solved problems are provided in ten chapters on basic physics topics, including External Beam Therapy Equipment, Photon Beam Physics, Radiation Dosimetry, Treatment Planning for External Beam Radiotherapy, and External Beam Commissioning and Quality Assurance. Each chapter provides examples, notes, and references for further reading to enhance understanding.


    • Consolidates concepts and assists in the understanding and applications of theoretical concepts in medical physics
    • Assists lecturers and instructors in setting assignments and tests
    • Suitable as a revision tool for postgraduate students sitting medical physics, radiation oncology, and radiology science examinations

    Robin Hill PhD, MACPSEM, MAAPM received his MSc (Medical and Health Physics) from the University of Adelaide and PhD from the University of Sydney. He is actively engaged in radiation oncology medical physics research, teaching and clinical activities including volunteer involvement in several IAEA activities. Dr Hill has authored/co-authored more than 60 papers in peer-reviewed journals with a particular interest in therapeutic kilovoltage X-ray beam dosimetry. He is accredited in radiation oncology medical physics by the ACPSEM.

    “This book is the third volume of a three-volume set that delves into medical physics. It presents a collection of problems and questions with answers and solutions on basic radiotherapy physics knowledge. The book consists of 10 large sections/chapters, 144 solved problems, and a bibliography. The book begins with the delivery equipment of standard conventional radiotherapy and transitions into treatment planning, special procedures, and radiobiology and radiation safety. The purpose of the book is to convey and emphasize basic radiotherapy physics concepts and their use in conventional radiation therapy treatments. The book executes this through problems and questions with provided answers and solutions for readers to practice and discover gaps in their knowledge. The book suits readers who have knowledge of the topic and seek

    further practice through problems and questions. The content and style are appropriate for young professionals in radiotherapy physics, including graduate students and medical physics residents, as well as radiation oncology residents who are preparing for their board certification examination. Medical dosimetrists and radiation therapy technologists will benefit as well.


    This volume plays an important role in the complete coverage of the subject. The solved problems and chapters on basic radiotherapy physics and its applications will undoubtedly benefit a wide audience.”
