Die Bestimmung von Organdosen bei Röntgenaufnahmen und computertomographischen Untersuchungen sowie die Berechnung der somatisch signifikanten Dosisindizes

Abstract

The risks from radiation exposure during radiological diagnosis has usually been estimated in relation to genetic changes. Relevant information has been expressed as the genetically significant dose. In this paper we attempt to produce an analogous measure for evaluating the somatic risk in the form of a somatically significant dose index for radiological and CT examinations. It is shown that, for both types of examination, the two risk factors may be entirely different.

“…The organ doses were measured in an Alderson-Rando phantom with rod-shaped CaF 2 thermolumi nescence dosimeters (TLD) (1x1x6 mm 3 , Harshaw Co., Wermelskirchen, Germany) (8). The dosime ters were positioned close to the tube, at the centre of the phantom and distant from the tube in the lung and in the mediastinum, respectively (Table).…”
