The article "Radiation Hazards to the Embryo and Fetus," by Liane Russell and Bill Russell, appeared in the journal Radiology in 1952. The first few sentences read: "THE RADIOSENSITIVITY of the embryo and fetus is a matter of great practical importance to radiologists, gynecologists, and obstetricians. It is unfortunate, therefore, that the literature on this subject is diffuse and contains numerous apparently contradictory reports and opinions."
