How do medical staff protect ct radiation?

CT stands for Computerized X-ray Tomography (X-ray is also used in nuclear magnetic resonance and interventional radiology). The gonads, lens, breast and thyroid in human body are particularly sensitive to radiation. If exposed to high-dose radiation for a long time, it may lead to cataract, sterilization, growth retardation, and even induce malignant tumor or leukemia. The influence of X-ray radiation on the fetus is more likely to cause embryonic disability, fetal malformation and brain dysplasia, and increase the probability of children suffering from cancer. But usually in the early stage of pregnancy, exposure to X-rays is more likely to cause major injuries, and the closer to the expected date of delivery, the smaller the impact.

When doing the examination, the dose used for X-ray fluoroscopy and photography is very small, which is within the safe range. The X-ray dose ingested by human body at one time is equivalent to the amount ingested by watching 1 hour TV. One dose of chest X-ray is equivalent to 0.5 times of 65438+X-ray photography; If you want to say harm, it is that a chest X-ray is equivalent to smoking three cigarettes.

Generally, the location of CT room and the structure of walls, doors and windows have certain standards and have certain protective effects. If they are all standard, there should be no problem. But it's better to be careful. You can't say for sure about many things.
