15 Νοε 2011 · Unborn babies are less sensitive during some stages of pregnancy than others. However, fetuses are particularly sensitive to radiation during their early development, between weeks 2 and 18 of pregnancy. The health consequences can be severe, even at radiation doses too low to make the mother sick.

1 Μαΐ 2023 · Solid understanding of how each imaging modality contributes to fetal radiation exposure, techniques to reducing radiation exposure in the fetus, and adverse consequences of high radiation exposure is critical in providing the most appropriate imaging studies for pregnant patients.
23 Αυγ 2023 · Fetal Risks From Ionizing Radiation. Significant potential harmful effects of ionizing radiation can be summarised into four main categories: Pregnancy loss (miscarriage, stillbirth) Malformation. Disturbances of growth or development. Mutagenic and carcinogenic effects.
1 Ιουλ 2007 · The potential biological effects of in utero radiation exposure of a developing fetus include prenatal death, intrauterine growth 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 ...
15 Νοε 2021 · Generally, intentional exposure of pregnant women is avoided as far as possible in both medical and occupational situations. This paper aims to summarise available information on sources of radiation exposure of the embryo/foetus primarily in medical settings.
In the early stages of pregnancy, embryo sensitivity is such that dosages of hundreds of rad per day of fractionated radiation therapy would not allow the embryo to survive. When exposures occur later in gestation, embryo sensitivity decreases but is still vulnerable to the cell-killing effects.
24 Απρ 2024 · Therefore, the risk following prenatal exposure may be considerably lower than for radiation exposure in early childhood [NCRP2013]. No reliable epidemiological data are available from studies to determine which stage of pregnancy is the most sensitive for radiation-induced cancer in the offspring [NCRP2013].
