Entrance surface dose (ESD) and effective dose (E) to premature infants were estimated at three neonatal intensive care units in Kuwait for three standard X-ray examinations--abdominal, chest and skull X rays using a simple water phantom. The ESD was found to vary between 58 and 102 µGy for abdominal X rays, between 51 and 102 µGy for chest X rays and between 58 and 145 µGy for skull examinations. These doses are comparable to the entrance skin doses published elsewhere. The E-values were estimated using normalised organ dose dataset from the National Radiological Protection Board. The E-values for abdominal, chest and skull examinations were in the ranges of 30-46, 20-36 and 8-18 µSv per examination, respectively. The risk of developing childhood cancers from each of the three examinations was estimated to be in the range (9-117) x 10-6 for infants undergoing 25 of these X-ray examinations during their stay in the NIC unit.
