The authors evaluate the radiation risk of children under 15 years whom they examined in 1984-1988 at the department of nuclear medicine in Jihlava by "in vivo" methods and compare the values with the radiation risk from the natural background and the Chernobyl disaster. The authors found that the radiation risk from a single renographic examination is by two orders lower than the radiation risk from the natural background in the course of a whole year, which is approximately double the risk ensuing from the Chernobyl disaster. The radiation risk of a single scintigraphic examination is insignificantly higher than the risk from the natural background in one year. Although the ratio of renographic examinations in the group accounts for 92%, it accounts only for 11% of the total radiation load of the group. Conversely scintigraphic examinations account for 88% of the total radiation load but only for 7.9% in the group. The total radiation load of the investigated group in one year due to administration of radiopharmaceutical preparations is lower than its contemporary total load from a the natural background and the Chernobyl disaster.
