Input: Question: Are -H2AX foci increased in lymphocytes in vivo in young children 1 h after very low-dose X-irradiation : a pilot study?
Answer: We found a significant induction of -H2AX foci in lymphocytes from post-CT samples of three very young children. When possible, CT exams should be limited or avoided by possibly applying non-ionizing radiation exposure techniques such as US or MRI.
Output:
yes
