The title of the document is misleading. When I saw External radiation exposure, I got a feeling that it will have dose quantities for medical also. I searched the document for words computed tomography, fluoroscopy, mammography, radiotherapy, KAP, CTDI, ESAK and did not find any of these words. Thus the document is not relevant for external radiation in medical applications. Please change the title so that others in the medical field do not get same feeling waste time looking into the document. Thanks
