Abstract
This project investigated the radiological impact of nuclear medicine patients on non-monitored personnel in hospital environments. More than 800 workers and 135 specific areas in three Quebec hospitals were surveyed daily during a six-month period with Geiger counters, TLD badges, and TLD chips. Average dose rates of up to 2.2 {mu}Sv/h were measured in some waiting areas. The radiation level of a nursing unit is a direct function of the ambulatory radioactivity carried by nuclear medicine patients. Three percent of the workers surveyed had a work-related dose in excess of 0.3 mSv/6 months (maximum 1.4 mSv/6 months). Over 88 percent were in the range between local background and 0.3 mSv/6 months. Less than 4 percent belong to groups of workers who were exposed to a level indistinguishable from background. Thus many workers surveyed in this study receive a work-related dose similar to those of medical workers monitored by Health and Welfare Canada. The average annual dose for these workers was 104 person-millisieverts. The authors recommend: better management of radioactive patients; the provision of information and education for all hospital workers having regular contact with radioactive patients; and the facilitation of the identification of nuclear medicine patients within the hospital environment.
