Abstract In paediatric radiology intestinal biopsies for the diagnosis of coeliac disease are performed using fluoroscopy. The radiation exposure to the child depends on the X-ray equipment. We report patient measurements from three different equipments (A, B and C) together with a phantom study simulating children of different thickness relative to age. The median values of the mean absorbed dose to the child in the irradiated volume were 1.2 mGy (A), 0.79 mGy (B) and 0.15 mGy (C). The results show that the increase in tube potential with increasing distance in one equipment decreases the dosage, and also that modern equipment should be employed. Particularly old image intensifiers should not be used. With an optimal choice of equipment the dosage to the child can be reduced fourfold. The combination of an optimal technique of sedation and an experienced operator can reduce the dosage tenfold.
