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 absorbed radiation dose level.
Most of the ways a pregnant woman may be exposed to radiation,such as from a diagnostic medical exam or an occupational exposure within regulatory limits,are not likely to cause health effects for a fetus.However,accidental or intentional exposure above regulatory limits may be cause for concern.Although radiation doses to a fetus tend to be lower than the dose to the mother,due to proteEstimating The Radiation Dose to The Embryo Or FetusPotential Health Effects of Prenatal Radiation ExposureCarcinogenic Effects of Prenatal Radiation ExposureHealth effects to a fetus from radiation exposure depend largely on the radiation dose.Estimating the radiation dose to the fetus requires consideration of all sources external and internal to the mothers body,including the following 1.Dose from an external source of radiation to the mothers abdomen.2.Dose from inhaling or ingesting a radioactive substance that enters the bloodstream and that may through the placenta.3.Dose from radioactive substances that may concentrate in maternaSee more on cdc.govExplore furtherCT and MR Pregnancy Guidelines UCSF Radiologyradiology.ucsf.eduPregnancy and Radiation Exposure - hpshpsHealth Effects of Prenatal Radiation Exposure - American aafpPregnant women IAEAiaeaRecommended to you based on what's popular FeedbackRadiation Exposure In PregnancyThe effect of radiation exposure during pregnancy also depends on the gestational age of the fetus.The embryo/fetus is most susceptible to radiation during organogenesis (2 to 7 weeks gestational age) and in the first trimester.The fetus is more resistant to What are the effects of radiation poisoning?What are the effects of radiation poisoning?The type and occurrence of the symptoms of radiation sickness and radiation poisoning typically depend on the amount of radiation that the person receives.In cases of smaller radiation doses,some of the more common effects are nausea,vomitingand conditions that result from lower blood counts such as infectionand bleeding.Radiation Sickness vs.Radiation Poisoning Be Aware of the What is radioactive warning sign?What is radioactive warning sign?Jump to navigation Jump to search.Skull and crossbones,a common symbol for poison and other sources of lethal danger (GHS hazard pictograms) Hazard symbols or warning symbolsare recognisable symbols designed to warn about hazardous or dangerous materials,locations,or objects,including electric currents,poisons,and radioactivity.Hazard symbol - Wikipedia
