[Prenatal irradiation of the rat with very weak doses of X-rays: lesions of the white matter].
The depth of the cingulum bundle, a myelinated substructure of the corpus callosum was found to represent a sensitive indicator of exposure to X-irradiation in utero at dose levels as low as 20 cGy. In such conditions, the origin of the anatomical damage is probably to be found in a disordered sequence of morphogenetic events rather than in mitotic cell death processes.
