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.

This web site is an information resource for study participants and researchers who are interested in learning more about the study.

News & Information
  • A shorter version of the USRT Fourth Survey questionnaire will be mailed in January 2014 to participants who have not yet returned their survey. Your prompt response is greatly appreciated.
  • Thank you to the 51,000 particpants who have already completed in the Fourth Survey. About 25,000 of you also completed a follow-up questionnaire about working with fluoroscopically-guided or radioisotope procedures. This additional detail will help us evaluate potential health effects that may be associated with these higher dose procedures.
  • Multiple Sclerosis in the USRT Cohort. The USRT Study is collaborating with researchers from the University of Washington to understand how environmental exposures, specifically ultraviolet light from sun exposure, affect the risk of multiple sclerosis. (Read more)
