Dr. Alice Stewart, Low-Level Radiation, and the Fetus

[ pour la version française ]           [ ENLARGE THE PHOTO ]

In the 1960s, Dr. Stewart conducted a pioneering study of women in the UK who received abdominal x-rays while pregnant. The data showed that a single x-ray in the first trimester of pregnancy increased the chances of childhood leukemia by 50 percent. Her results were attacked not by medical doctors or radiologists, but by officials in the nuclear industry, who had assured people for decades that low-level radiation was harmless. Today, her findings are uncontroversial, having been amply confirmed by other medical data.
