background with the increase of x-ray use for medical diagnostic purposes, knowing the given doses is necessary in patients for comparison with reference levels. the concept of reference doses or diagnostic reference levels (drls) has been developed as a practical aid in the optimization of patient protection in diagnostic radiology. objectives to assess the radiation doses to neonates from dia...

The objective of this study was to evaluate the association between in utero diagnostic X-rays and childhood acute lymphoblastic leukemia (ALL) and the less well-studied relationship of this malignancy to preconception and postnatal diagnostic X-rays or fetal ultrasound exposures.
