A Review on the Effect of Radiation in Pregnant Women

Sana Iqbal

The effects of ionizing radiation on the fetus, the prenatal period, parental exposure, the pregnant clinician, and the pregnant patient are discussed in the context of their exposure to radiation. Seasons and Vitamin D are factors that are directly and indirectly related to Ultra Violet (UV) radiations and can affect pregnancy. The potential biological effects of in utero radiation exposure of a developing fetus include prenatal death, restriction, small head size, mental retardation, organ malformation and childhood cancer. The risk of each effect depends on the gestational age at the time of exposure, fetal cellular repair mechanisms, and the absorbed radiation dose level. A comparison between the dose levels associated with each of these risks and the estimated fetal doses from typical radiologic examinations lends support to the conclusion that fetal risks are minimal and, therefore, that radiologic and nuclear medicine examinations that may provide significant diagnostic information should not be withheld from pregnant women. However, although the risks are small, it is important to ensure that radiation doses are kept as low as reasonably achievable.
