DCEG investigators in the Radiation Epidemiology Branch carry out research designed to identify, understand, and quantify the risk of cancer in populations exposed to ionizing radiation (e.g., x-rays, CT scans, radon, and cosmic rays) and non-ionizing radiation (e.g., radiofrequency and extremely low-frequency or power frequency) from various sources, including:
In addition, DCEG researchers perform radiation dosimetry research in support of epidemiological studies.
Studies of non-ionizing radiation include:
