Abstract | |||
Background: In 1982, the Radiation Epidemiology Branch, NCI and the University of Minnesota initiated a study of cancer incidence and mortality among radiologic technologists in the United States. The primary objectives of this study were to quantify the carcinogenic risks of long-term, low-dose, fractionated radiation exposures experienced through occupation and to determine applicability of current risk estimates which are based primarily on studies of individuals experiencing single or short-term high-dose exposures, such as atomic bomb survivors and medically-irradiated patients. Study Population: A cohort of approximately 146,000 technologists who were certified by the American Registry of Radiologic Technologists (ARRT) for at least two years during the period 1926-1982 was identified for study. |
