In a field where comprehensive study guides for board exams are severely lacking, this book does an excellent job of filling that void for the American Board of Radiology (ABR) and Medical Dosimetry Certification Board (MDCB) exams. ... The primary audience is dosimetry candidates taking the MDCB exam as well as medical physicists taking part I (and to a lesser extent part II) of the ABR exam.
