Many industries require health certificates in order to ensure that customers can consume safely and healthily. Then, if you get a health certificate and have a chest X-ray examination when you are pregnant, don't worry. It is recommended to observe for a few days to see if there is any miscarriage. If not, screening for Down syndrome should be done at 14- 19 weeks of pregnancy, and screening for abnormal thinking should be done at 22-26 weeks of pregnancy.
And in the case of knowing pregnancy, rest at home for about 2 months before going to work, because abortion is prone to occur in the first trimester, and the embryo may not develop well due to the influence of X-rays, so proper rest is necessary. If Down's screening and malformation screening do not find fetal problems, the child can be born. In the future, you must have regular prenatal examinations and raise your fetus scientifically.
