[Radiation dosage of premature infants caused by roentgen imaging of the thorax].

The X-ray pictures of the thorax from premature infants must be prepared by conditions of neonatal intensive care. For this X-ray pictures are available very often single-puls generators only. The radiation exposure is dependent prominently on the type of the generator. The radiation exposure was compared between single-puls generators and 6-puls generators. The dosimetry was performed with CaF2-thermoluminescent dosimeters. The results of measurement demonstrated: In the radiation fields the radiation exposure is considerable higher by the single-puls generators than by the 6-puls generators. The indication to X-ray pictures of the thorax from premature infants under conditions of bed-side with single-puls generators must be very accuratly.
