One of the earliest hospital-based radiology services in the world was set up in 1899 in Newcastle, at the long since demolished Forth Banks Infirmary. Remarkably, a day log of examinations performed in this department survived, being re-discovered many years later on top of a filing cabinet in the modern x-ray department that replaced it. This presentation describes the use of the data from the log to make estimates of patient and staff radiation dose using a combination of estimation from historical data plus physical evidence from surviving contemporary x-ray equipment. These results from 1899-1902 show patient doses of a magnitude unacceptable by modern standards, but not perhaps as high as might be guessed at merely by noting the long exposure times in the original log. The record tells a story of the earliest radiographers struggling with unreliable equipment but still developing a vital diagnostic service. The dangerous level of staff irradiation for these pioneers is confirmed.
