This book includes topics on selecting the best radiotherapy treatment target and normal organ volumes for curietherapy (brachytherapy) and how to estimate and eliminate the human and monetary cost of pollution oncology. Air pollution has become a major threat to global health and deserves an immediate and a global effort to solve. This book belongs to a series of books and papers I call the best of us. I hope to find the best in treatment, in places, in our spirits and memories that will bind us and will help to prevent and remove some of the pain and suffering associated with unnecessary death, and sickness. For the best of all of us, RC@Brooklyn 9.9.2015.
