Abstract
In diagnostic X-ray examinations, dose assessments for pregnant female and fetus are realistically difficult, and related research is also lacking. Therefore, in this study, the purpose of the simulation was to analyze the dose and fetal dose for pregnant female during abdominal X-ray examination. Based on the data presented in ICRP 89, this study produced phantom reconstructed of the existing prenatal phantom, which was used to analyze the evaluation of the organ dose and fetal dose of pregnant female according to pregnancy week and the difference between the dose of the existing phantom and the reconstructed phantom. As a result, the abdominal X-ray test showed a tendency to show higher doses for organs close to the direction of the source joining. In addition, it was confirmed that fetal doses in posteroanterior position were reduced by more than 65% compared with anteroposterior position.
