We know that the most sensitive
to radiation are actively fissile cells. At the time of division they are
almost defenseless to the effects of many environmental factors, including
radiation. An adult of such cells are relatively few and their damage to small
doses of radiation are not always fraught with consequences. The child in the
womb to share cells of all organs and tissues. Nature invented a catchy way to
protect a fertilized egg from the possible consequences for mankind. At the
early stage of embryo development is the principle of «all or nothing». So if
fluorography (especially classical, film) in pregnant was held after the
expected date of menstruation, it is recommended that medical and genetic
counseling. So, during pregnancy should be avoided impacts of X-rays. These
studies in pregnant hold only if absolutely necessary, also only on strict
clinical indications. Relatively safe in this respect the second half of
pregnancy when the unborn child has already been formed, all organs and
systems, and therefore less likely negative impact of X-rays on the fetus.
You can not attract pregnant to
participate in the X-ray. It is about maintaining aid to children and
terminally ill relatives during the study. X-ray studies, regardless of the
duration of pregnancy only when necessary for the provision of ambulance or
emergency room or in dealing with the issue of abortion.
According to regulatory
documents, for women aged under 45 years of working with radiation sources,
imposed additional restrictions: the dose received by the result of two months
undetected pregnancy, should not exceed 1 mSv. Occasionally there are cases
where the projected level of fetal exposure exceeds 0.1 Sv (100 mSv). Such
cases may occur if necessary repeat X-ray studies (such as X-rays) of the
digestive system, urinary tract, pelvic area with serious illnesses. In such
cases, the doctor is obliged to warn the patient about the possible
consequences of the harmful effects of radiation on fruit and strongly
recommend abortion.
For example, does not affect
whether the health of the fetus pictures at the hands of a breakthrough mother?
We should not, if the study had been carried out correctly, quote from the
body. X-ray radiation has adverse impact only with the direct impact on the
child. The study will not have any impact on the properties of milk, so the
study could take place without fear of consequences.
X-ray of the teeth during
pregnancy increases the risk of the child's birth weight was below the norm,
say scientists. Previously, researchers have noted a link between the birth of
babies with low birth weight and the passage of X-ray, but images of teeth were
considered harmless.
By opinion of scientist team
from the University of Washington, the refusal of pregnant women from x-ray at
the dentist can reduce the risk of giving birth to low birth weight by 5%. Scientists
have published their findings in the Journal of the American Medical
Association. The scientists studied the medical history of women treated at the
dentist from January 1993 to December 2000. About 2% of women, whose children
were born with low birth weight, did X-rays of teeth.
Scientists have found that,
women whom dentists are doing dental X-ray image, apparently in 3.5 times more
children are born weighing less than two and a half pounds than women who did
not do during pregnancy X-ray teeth.
"The biggest dose of
radiation to which they were subjected, is approximately equal to radiation,
which exposed passengers, 16 times fly from New York to London and back,"
- he indicates.
Scientists point out that their
findings contradict the prevailing view that the weak X-rays are not harmful to
pregnant women, if reproductive organs are not exposed to radiation. Previously,
researchers have found that the radiation received when Roentgen for diagnosis,
for example, when problems with the backbone, has also led to the birth of
children with low birth weight.
Pregnant better to avoid dental
X-ray, and resort to it, only in exceptional cases. Dentists make X-rays, which
found it necessary to diagnose, and the majority of dentists in the treatment
of pregnant women are especially wary. Women should alert the doctor that they
are pregnant or think that might be pregnant.
