The Tolerance Dose

Abstract : In the development of the science of radiotherapy, a special nomenclature has grown up, which, for the most part, is clear and unambiguous to the doctors and physicists engaged in the field. For special reasons, some of the quantities involved were defined in a different manner from that in which analogous quantities in pure physics would have been handled. The present project makes it a matter of general interest to correlate these two aspects. Some account of the terms used will therefore be given before proceeding to the main discussion.
