12 Questions
The embryo is most sensitive to the lethal effects of ionizing radiation during the fetal development stage.
False
Irradiation can cause functional disabilities before 11 weeks of gestation.
False
The most likely outcome of cellular damage to the embryo in the first three weeks of pregnancy is enhanced cellular growth.
False
The phase of pregnancy development involving days 0 to 14 and having a relatively small number of cells in the embryo is called organogenesis.
False
Radiation exposure before or immediately after implantation of the embryo can cause enhanced cognitive abilities in the live-born child.
False
Malformations typically occur at a dose threshold of 50-100 mGy.
False
During 8-25 weeks post-conception, the central nervous system is not particularly sensitive to radiation.
False
Increasing radiation dose is associated with a general upward shift in IQ.
False
Severe abnormalities were observed between 12-16 weeks of gestation due to radiation exposure.
False
To cause a miscarriage during the fetus sensitivity period to x-rays, exposure to over 100 mSv is necessary.
False
The fetus becomes more resistant to the effects of radiation at 16 weeks on in pregnancy.
True
Between 16-23 weeks post-conception, the central nervous system is particularly sensitive to radiation exposure.
False
