Question

Quizplus · Accepted Answer

During the first trimester, organ and tissue development are occurring rapidly and cell division is at its highest rate. This means that any exposure to radiation can cause greater damage to the developing fetus, which can lead to birth defects or even miscarriage. Additionally, during the second and third trimesters, the fetus is better protected by the mother's abdominal wall and the amniotic fluid.
