How to reduce the harm after X-ray irradiation

As we all know, X-rays have a certain destructive effect on biological cells. Excessive exposure to X-rays will affect physiological functions, cause chromosomal abnormalities and lead to cancer. But proper irradiation will not affect human health. Because the dose used by medical staff for X-ray fluoroscopy and photography is very small, only within the safe dose. In particular, occasional chest x-ray, gastrointestinal examination, bone X-ray or angiography will not cause adverse reactions. Moreover, the X dose used for filming is not completely absorbed by people, most of it penetrates the human body, and only a small part is absorbed by the human body. If we want to say a specific value, it is that the human body really absorbs only a few tenths or even less of the dose used. Moreover, the radiation inspection equipment used in major hospitals in Suzhou, such as the First Affiliated Hospital of Suzhou University, has long been replaced by digital radiography (CR) and direct digital imaging (DR), and the radiation amount has been greatly reduced, accounting for only the original 1/7. So to be exact, it is completely correct for normal people to do ct once a week, and it will not affect their health. Director Guo emphasized that medical X-rays will never affect people's health during examination and treatment, and the public need not have any concerns. The main reason why primary school students cancel chest X-ray examination is that Guo Liang thinks that the radiation dose used in chest X-ray examination is one aspect, but the main reason is probably that the resolution of chest X-ray examination is lower than that of filming, and there is only one doctor to diagnose it from beginning to end, so the accuracy of diagnosis can only be based on the doctor's personal level, which leads to a higher error rate, and it is not conducive to follow-up like filming. Who is not suitable for X-ray examination? Guo Liang also pointed out that although it is difficult to determine the cause of physical discomfort, X-ray examination can be done to reassure yourself. But everything has two sides, and radioactive inspection is no exception. Some people should pay a little attention to X-ray examination. For example, pregnant women should not have an X-ray examination within three months of pregnancy, because the fetus at this stage has not yet formed. If pregnant women receive too much X-ray radiation, it will easily lead to mental retardation or microcephaly of the fetus, which will lead to an increase in the incidence of cancer after birth. In fact, X-rays are everywhere in our daily life. Television, computers, mobile phones, microwave ovens, and even sunlight and moonlight endowed by nature also have X-rays. X-ray hazards of some objects in daily life can not be ignored, such as not letting children get too close to the microwave oven at home; Choose building materials carefully, such as granite with high radiation, and use them carefully; Don't watch TV or use the computer for a long time. If it is necessary for work, try to work for an hour or two and let yourself rest for ten minutes.
