Biological dosimetry after extensive diagnostic x-ray exposure.
The yield of chromosome aberrations (dicentric and ring chromosomes) was determined for five patients who had been extensively exposed to diagnostic x rays. Remarkably high aberration yields were obtained for each of them leading to correspondingly high equivalent whole body doses ("biological dosimetry"). The contribution of iodized contrast media and computing tomography to the biologically estimated doses is discussed.
