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
More than 110,000 radiologic technologists — current
and former — have participated in this study by completing one or more of
the questionnaire surveys about their work history, health status, and
other factors. Through their participation in the study, we are learning
more each year about radiation and health.
