Radiation exposure of pregnant women in hospitals

Does it matter if you get pregnant after a month of dental radiography? How much does X-ray radiation affect pregnant women? Generally speaking, radiation is very harmful to pregnant women, which will lead to changes in fetal genes and serious malformations. But if pregnant women take dental photos before pregnancy, will it affect their children? Does one month after dental filming have an effect on pregnancy? Does the X-ray radiation of dental photographs have a great influence on pregnant women? How big is it? Come and have a look with me.

According to the regulations of the International Radiological Commission, the radiation limit of each person in one year cannot exceed 5 millisieverts, that is, about 5,000 microsieverts, and the radiation dose of a dental piece is 5 microsieverts. Therefore, relatively speaking, the radiation dose of dental tablets is actually not high, but it is actually a very small amount. Moreover, we live in nature, and there is radiation in nature all the time. Every year, the radiation received by human body will reach about 4 millisieverts, and the proportion of physical examination radiation is relatively small compared with that brought by other natural environments, which is about 15%. For a very simple example, we watch TV for about 1 microsievert a year, in high altitude areas, such as the central and western Inner Mongolia and the Qinghai-Tibet Plateau.

If it is a pre-pregnancy dental tablet, it has no effect; Generally speaking, it doesn't matter much if you find yourself pregnant after a month of dental surgery. Eating folic acid can prevent fetal malformation. But for pregnant women, it is best not to take dental films, because the sensitivity of the fetus is different from ordinary people. If it is because of special reasons, such as the threat to the fetus caused by untreated tooth infection, you can choose to take dental tablets after three months of pregnancy. If the situation is not so urgent, it is still recommended that the baby be cured after birth.

Does B-ultrasound have radiation during pregnancy, and does it affect the fetus? Does C-arm radiation in operating room affect pregnant women?

I will do various tests when I am pregnant, but for pregnant women, there are too many things to pay attention to, and some mothers are very worried. Those tests in the hospital will have radiation, which will have an impact on the baby's growth and development. Today, we talk about pregnancy. Does the B-ultrasound have radiation? Does it affect the fetus? Does the radiation of C-arm machine in operating room affect pregnant women?

First of all, B-ultrasound is a non-invasive examination. The ultrasonic intensity emitted by the probe used in the hospital is less than 10mW/cm, which is relatively small and has no cumulative effect. Moreover, every time pregnant women do B-ultrasound, the examination time is also very short, which is not enough to affect the fetus.

For the C-arm machine in the operating room, there is radiation, but for pregnant women, the radiation amount of an operation is tolerable. However, if the pregnant woman is a doctor or nurse in the operating room, it is recommended to change jobs temporarily, because this radiation will accumulate, which is very unbearable for the baby and will have a great impact.

If you simply do a pregnancy check-up in the hospital, the expectant mother doesn't have to worry. The doctor will grasp the amount. The pregnancy check-up is to make the baby grow sturdily, so the radiation dose will definitely not exceed the standard, and the expectant mother can rest assured.

Does ct have radiation effects on pregnant women? Is it harmful? Does petct have great radiation to pregnant women?

With the improvement of living standards, people will regularly check their physical condition, even if it is not a regular physical examination, they will need to check their bodies for various reasons. So how long can I get pregnant after CT? Does CT have radiation on pregnant women? Is it harmful? Does CT have any great influence? Does PETCT have great radiation to pregnant women? Let's take a look together.

First of all, CT is the abbreviation of computed tomography, which belongs to a kind of radiological examination. A CT examination of normal people will not have much impact on the body, but the radiation resistance of the fetus is different from that of normal people. In the process of fetal organ formation, the resistance to radiation is the weakest, about 8 ~ 25 weeks after pregnancy, and radiation is the most likely to cause fetal central nervous system abnormalities. Moreover, if the amount of radiation is large, it will cause fetal chromosome variation, leading to fetal malformation or death.

PET is the abbreviation of positron emission computed tomography, which belongs to nuclear medicine and contains the optimal combination of PET (functional molecular image) and CT (anatomical image). So the radiation of PETCT = the radiation of PET+the radiation of CT, in which the radiation of PET is about 6 to 7 millisieverts; The radiation of CT is obviously different in different modes, among which the radiation is about 6 or 7 millisieverts at low doses; Therefore, the radiation dose range of PETCT is about 10- 15 millisieverts. This amount of radiation is still very large for pregnant women.

Does oral ct radiation affect pregnancy? Does the pregnant woman have radiation outside the ct room?

Everyone knows that radiation does great harm to human body, especially to pregnant women, and it is the number one enemy. At present, the largest amount of radiation we are exposed to is ct. If oral ct is done in early pregnancy, will oral ct radiation affect pregnancy? Is there radiation when pregnant women stand outside the ct room during hospital examination?

Ct has a great influence on pregnant women. Oral ct will be smaller, but it can't be careless. If you want to get pregnant after oral ct, it is best to get pregnant every 6 months or so. If a pregnant woman is pregnant, she must have an oral examination, so don't worry too much. Generally speaking, after the most critical time of fetal development in the first three months, you can do the examination. They must wear protective clothing to avoid direct radiation to the fetus during the examination. Of course, this is a last resort. If it's not so urgent, you can wait until the baby is born to treat your teeth.

Generally speaking, the walls and doors of radiology department are specially customized, and the walls and doors of each ct room need to pass the national inspection. We can also see that the door of radiology department is different from other places. During the radiation inspection, the door is closed, and the radiation room will not affect people outside through the wall, so the expectant mother can rest assured.
