About the Study
The U. S. Radiologic Technologists Study is a collaborative effort between the University of Minnesota, School of Public Health, the National Cancer Institute (NCI), and the American Registry of Radiologic Technologists (ARRT). This study began in 1982 by identifying 146,022 current and former radiologic technologists who were certified by the ARRT for at least two years from 1926 to 1982. The study cohort includes technologists certified in radiography, nuclear medicine, radiation therapy and other imaging specialties.
The key goal of the study is to understand how repeated low-dose occupational ionizing radiation exposures, such as those potentially experienced by radiologic technologists, are related to cancer and other health conditions.
This study is unique because:
The study conducted four major surveys during 1983-2014. Additionally, follow-up questionnaires were sent to Fourth Survey responders who reported working with radioisotope or fluoroscopically-guided procedures to obtain more detailed information about work practices and exposures related to these procedures.
