About half of the total medical irradiation doses is said to be accounted for by the genetically significant dose during the fluoroscopy of alimentary canals. It is important for us radiological technicians, therefore, to know how irradiation doses during the fluroscopy influence on the patient's gonads depending on their conditions and ages. This research can be a step toward a better medical treatment. Firstly, of all the patients treated with the gastric fluoroscopy, the percentage of the reproduction patients whose ages are 40 or less was calculated. Then the study was made as to whether there was any difference in irradition doses on the gonad of a patient, depending on wheter he was over 40 or under 40. This study also revealed whether the therapist has given careful consideration to the genetic influence of the irradiation dose. As a result, it was found that radiologists has given special attention to the progenitive condition of the patient by reducing the time needed for fluoroscopy. However, no difference in irradiation doses based on the patient's age was observed in the treatments by non-radiologists.
