Brain Tumor Deaths Not Linked to Exposure

Apr 04, 2017

In a survey of more than 110,000 radiologic technologists over several decades, a study published in the American Journal of Roentgenology has found little association between occupational exposure to radiation and deaths related to brain tumor.

The study population included 83,655 female and 26,642 male U.S. radiologic technologists who were certified for at least two years as of 1982. Researchers followed the study group through 2012. Among the group surveyed, 193 technologists died of a malignant intracranial neoplasm during the median 26.7-year follow-up period.

Lead author Cari Kitahara, Ph.D., of the National Cancer Institute, said in the study, “Occupational brain doses through 1997 were based on work history, historical data, and, for most years after the mid-1970s, individual film badge measurements.”

The study concluded that cumulative, protracted occupational radiation exposure was not associated with mortality due to malignant intracranial tumor.
