The U.S. Radiologic Technologists Study, which began in 1982, is a collaborative effort between the University of Minnesota, the National Cancer Institute, and the American Registry of Radiologic Technologists to investigate potential radiation-related health effects from low-dose occupational radiation exposure.

Today, more than 90,000 radiologic technologists — current and former — continue to be followed through periodic surveys about their health status and other factors. Through their participation in the study, we are learning more each year about radiation and health.
