![]() The other aspect of the study that has been ongoing and we hope to look at is the genetic aspect. We wanted to get a better understanding of any risk long-term, low-dose radiation can cause. Also there are not that many studies where one of the populations is women most radiologic technologists are women. There is a lot of research about higher exposure in certain industries such as nuclear and in atomic bomb survivors, and in patients who get large doses in their medical care.īut there are not that many studies of people who receive exposure in the course of their work in the medical field, who get relatively low doses but protracted over many years. H: Can you explain what this study is about and what you are trying to find out?īA: One of the things we know of all environmental exposure studies is that ionizing radiation can cause cancer. This is a jointly run study with the National Cancer Institute but I became involved when the previous director, who started the study, left the university. Healthecareers: How long have you been the study director?īruce Alexander: Since the summer of 1999. Alexander talked about his work in a telephone interview. Information about the study is available at Dr. What the study has not shown yet is why some people are more susceptible to cancer and why. The study said that the elevated risks could be related to the occupation, or it could be because they work in medicine, R.T.s were able to have better access to healthcare and early detection. Some cancer types, such as breast cancer in women, and melanoma and thyroid cancer in both men and women, were slightly higher than expected. Some cancer types, such as lung, rectum and oral cavity cancers, were significantly lower than expected in both male and female technologists. radiologic technologists were about the same as in the general population. radiologic technologists, was to determine whether repeated low-dose ionizing radiation exposure was related to cancer and other diseases.Īmong other findings, the study showed that between 19, cancers in U.S. The original goal of the study, which began in 1982 and has surveyed 146,000 U.S. The 30-year old study, conducted by the University of Minnesota, the National Cancer Institute and the American Registry of Radiologic Technologists (ARRT), is the world’s-largest and most comprehensive study of people who are exposed to radiation in the workplace. Study shows no evidence that exposure to ionizing radiation in the workplace under proper controls causes more cancerīruce Alexander, PhD, is an epidemiologist and professor at the University of Minnesota School of Public Health and director of the U.S.
