Radiation doses for a potential conceptus were estimated by using dose data obtained in anthropomorphic phantoms simulating pregnancy at the first, second, and third trimesters. Dose measurements were carried out using thermoluminescent dosimeters. For a typical examination, the average radiation dose to the conceptus was &lt;1 mGy in all periods of gestation. Average excess fatal cancer was 14.5\/10\n            <jats:sup>6<\/jats:sup>\n            unborn children irradiated during the first postconception weeks. Corresponding values for the second and third trimesters were 30 and 55.7\/10\n            <jats:sup>6<\/jats:sup>\n            , respectively.
