Exposure to medical imaging radiation is a concern in both adults and children. However, radiation exposure in children is of a greater concern because they are more sensitive to radiation than adults. In addition, children have longer life expectancy than adults. With repeated exposure or accumulated exposure to radiation, children may be more likely to develop health problems in the future.
Life time risk of developing cancer increases when a patient undergoes more frequent X-ray exams and at larger doses, according to the FDA. Women who are exposed to the radiation may have higher lifetime risk for developing radiation-associated cancer than men after receiving the same exposures at the same ages.
While experts believe that the risk of developing cancer with radiation exposure is relatively small, radiation exposure through these medical imaging tests should never be taken lightly.
