Tóm tắt

Bài báo trình bày phân tích về mối tương quan giữa các chỉ số tế bào học trong lymphocyte và nồng độ glutathione giảm trong huyết tương của máu ngoại vi ở trẻ em sinh ra sau vụ tai nạn Chernobyl. Các hệ thống được nghiên cứu trong quần thể trẻ em đã thể hiện những phản ứng khác nhau đối với bức xạ mức thấp từ các bà mẹ sống trong điều kiện ô nhiễm đồng vị phóng xạ (từ 1 đến 20 Ci/km2 của 137Cs). Các liều bức xạ thấp tích tụ từ các bà mẹ (dưới 30 cSv) tỏ ra có ảnh hưởng rõ rệt hơn đến các hệ thống được nghiên cứu ở trẻ em so với các liều bức xạ cao (từ 30 đến 60 cSv).
