What are the hazards of x-rays to the human body? Good health is very important in life. It is a way for us to maintain body functions. There are some substances in life that are harmful to the human body. Let's take a look at the harmful effects of x-rays on the human body. What are the hazards of x-rays to the human body 1

It is believed that radiation is very harmful to the human body.

Excessive X-rays can cause hematopoietic dysfunction, affect human gonadal function, damage the human lens and cause cataracts, and even increase the prevention rate of tumors. Especially if pregnant women are exposed to a large number of X-rays, the fetus in the belly will be malformed.

Hazards:

Long-term exposure may cause terrible consequences of infertility and fetal malformations. Male sperm may also have certain effects on X-rays. reaction, may lead to infertility.

If a patient undergoes more X-ray examinations, especially within a short period of time, it may lead to dire consequences of cell canceration.

Be sure to avoid use by pregnant women as much as possible, because X-rays contain a large amount of radiation, which may cause cancer in the cells of pregnant women and babies, which is not conducive to the development and growth of babies.

Protection:

Since patients are not professionals, they should seek medical treatment promptly when they experience uncomfortable symptoms, conduct appropriate examinations according to medical advice, and avoid unnecessary examinations.

Patients should pay attention to protective measures when undergoing X-ray examinations, wear aprons, lead suits and other professional protective equipment, and shield the parts that do not need to be exposed to examination from radiation, thereby reducing the risk of radiation. harm and protect human health.

The X-rays that people receive in life include sunlight and X-rays when flying on airplanes. The human body can receive 3 to 4 millisieverts of radiation a year, as long as the exposure to X-rays does not exceed the human body's maximum intake. It will not have any impact on the human body. Especially when people undergo X-ray examinations, the dose at this time is within a safe range, and corresponding protective measures will be taken.

So don’t worry, the dose of radiation in taking X-rays is negligible. CT has the highest radiation among all examination items. If the irradiated parts are the same, the radiation of CT is about 100 times that of within. What are the harms of x-rays to the human body 2

1. They can kill normal cells in the human body. X-rays contain certain radiation. When we perform X-ray examinations, these radiations will cause damage to normal cells in the human body, leading to cell reduction and death. In particular, white blood cells are easily killed by X-rays.

2. Decreased immunity. Because when people take X-rays, their body cells are severely damaged, so under such circumstances, people's immunity is prone to decline, and when immunity declines, people's bodies will be susceptible to viruses and The invasion of bacteria can lead to various diseases in the body, and in severe cases, it can also lead to the occurrence of malignant tumors and cancer.

3. If a woman undergoes an X-ray examination when she is not sure she is pregnant, it is very likely that the fetus will be miscarried or miscarried after a later diagnosis. It's a developmental malformation. Therefore, if a woman is not sure that she is pregnant, it is best not to have an X-ray examination. If she must do it, she must follow the doctor's advice before having the examination.

Therefore, when taking X-rays, you must take them according to your actual situation and control the number of shots, so as to reduce the damage to the body. If you only take an X-ray once in a while, it won't cause much harm to your body. Even if it does, it will only be a little bit. As long as you pay attention to rest for a period of time, it can return to normal.

It turns out that this small tube is called a "radiation measurement tube" and is specially used to measure the amount of X-rays that professional staff take in every day. It will be taken down every once in a while and measured. Whether the X-ray dose received by this worker exceeds the standard. Director Guo told reporters that under normal circumstances, the results measured are within the normal range. For professionals like him who have worked for many years, every measurement is "passing".

Guo Liang said that in modern medicine, X-rays can be said to be very popular, showing their importance everywhere. Radioactive examinations that are familiar to people, such as CT, MRI, and interventional radiation, are constantly used in clinical medicine, greatly improving the diagnosis rate of diseases. Their daily job is to examine various abnormalities in the patient's body through the penetrating "eyes" of X-rays.

Are medical X-rays harmful to the human body?

Recently, radiation protection experts in Guangzhou and Shenzhen have also called for the annual physical examination of children and chest X-rays to be stopped as soon as possible. As a result, radioactive testing, which has always been quite mysterious, instantly became the focus of people's attention. Many readers have called and written to ask our reporter: Are X-rays harmful to the human body? Will exposure to X-rays cause cancer? In response to these issues, the reporter specifically interviewed Associate Professor Guo Liang, director of the Department of Imaging Medicine at the First Affiliated Hospital of Suzhou University.

A CT scan once a week will not affect health

Everyone knows that X-rays have a certain killing and damaging effect on biological cells. After excessive exposure to X-rays, , will affect physiological functions, cause chromosomal abnormalities, and lead to the occurrence of cancer. However, moderate exposure will not affect human health. Because when medical staff perform examinations, the dose used for X-ray fluoroscopy and photography is very small and is limited to a safe dose. In particular, an occasional chest X-ray, gastrointestinal examination, bone X-ray or angiography will not cause adverse reactions. Moreover, the dose of It’s not even a few ten thousandths of the dose used.

Moreover, the radiological examination equipment used by 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). The amount of radiation is much higher than before. It has been reduced a lot, accounting for only 1/7 of the original.

So to be precise, if a normal human body has a CT scan once a week, it will definitely not affect health. Director Guo emphasized that when medical X-rays are used to examine and treat people, they will never affect people's health, so citizens do not have to worry.

The main reason for the cancellation of chest X-rays

Regarding the cancellation of chest X-rays in physical examinations for primary school students, Guo Liang believes that the high radiation dose used in chest X-rays is one aspect, but the main reason is probably Or because the resolution of a chest X-ray is lower than that of a chest X-ray, and only one doctor makes the diagnosis from start to finish. The accuracy of the diagnosis can only be based on the doctor's personal level, resulting in a relatively high error rate, and it also Unlike taking a X-ray, the data can be retained, which is helpful for follow-up consultation.

Who should not undergo X-ray examination?

Guo Liang also pointed out that although it is difficult to determine the cause of physical discomfort, you can have X-ray examination to reassure yourself. But everything has two sides, and radioactive examinations are no exception. Some people should pay more attention when doing X-ray examinations. For example, pregnant women should not undergo X-ray examinations within 3 months of pregnancy because the fetus at this stage has not yet formed. , if pregnant women receive too much X-rays, it is easy to cause mental retardation or microcephaly in the fetus, leading to an increased incidence of cancer after birth.
