What is the specific mechanism of damage to human cells in X ray in X CT?

It is easy to cause genetic mutations in the body's cells

X-ray is commonly known as the shooting of Zhou He Ji Yu**, the photo book socks X-ray.

CT Scan is a CT scan <>

X-ray radiation is harmful to the human body, but it is not that powerful. If it is not directly irradiated under the X-ray, there will not be a lot of harm, usually more outdoor activities, receiving some sunlight can eliminate some damage, a month will not be much harm, generally people feel no strength, very tired, poor spirit, poor appetite, just go to check the white blood cells, mainly white fine, I tell you those situations, you do not have a psychological effect.

Hope it helps.

When X-ray irradiates the biological organism, the biological cells can be inhibited, destroyed and even necrotic, resulting in different degrees of physiological, pathological and biochemical changes in the organism. Different biological cells, with different sensitivities to X-rays, can be used for certain diseases in the human body, especially tumors. At the same time of using X-rays, people have found that the problems that cause radiation injuries such as hair loss, burns, visual impairment of staff, leukemia, etc., should also pay attention to the damage to the normal body while applying X-rays, and pay attention to taking protective measures.

X-rays are a stream of particles produced due to the transition of electrons in an atom between two energy levels with a huge difference in energy, and are electromagnetic radiation with a wavelength between ultraviolet and rays. Its wavelength is very short, about between angstroms. It was discovered by the German physicist Roentgen in 1895, so it is also known as Roentgen rays.

Roentgenium rays have a high ability to penetrate many substances that are opaque to visible light, such as ink, paper, wood, etc. This invisible ray can cause many solid materials to fluoresce visibly, making photographic negatives sensitive and ionizing air. Wavelengths smaller than angstroms are called ultra-hard X-rays, those in the angstroms range are called hard X-rays, and those in the 1 100 angstroms range are called soft X-rays.

X-rays were originally used in medical imaging, diagnostics, and X-ray crystallography. X-rays are also harmful rays such as ionizing radiation. It is often used in medicine for fluoroscopy and for flaw detection in industry.

X-rays can be detected with ionometers, scintillation counters, and photosensitive latex. X-ray diffraction has become an important means to study crystal structure, morphology and various defects.

1. The welder's workshop should always be ventilated and dry, and the welding machine must be checked for leakage and lap iron before the welding machine is closed, and whether the binding post is loose, and then the welder can be closed. 2. When performing electric welding, you must wear: (1) mask (2) gloves (3) foot protection to prevent arc light from stabbing eyes and burns**, and preventing burns caused by sparks.

3. Careful care must be taken when knocking on the welding agent skin to prevent splashing burns. Fourth, it is strictly forbidden to enter the basement of the acetylene generator with fire to prevent **. 5. The safety flashback preventer must be checked regularly to be safe and reliable.

6. When carrying the oxygen cylinder, it is necessary to add a safety shockproof ring, and it is strictly forbidden to roll, fall, knock, and violently shake the oxygen cylinder, and it is strictly forbidden to touch the oxygen cylinder with oil hands and oil, and it is strictly forbidden to expose the oxygen cylinder to the scorching sun. The ignition source of gas welding needs to be 3 5 meters away from the oxygen cylinder to prevent **. 7. When welding oil barrels and oil tanks, the oil scale must be removed before welding, and the welding must be carefully applied to prevent the first grade.

8. Before leaving work, the power supply must be cut off, and oxygen and acetylene must be turned off.

Yes, a CT scan is not very harmful.

When doing the examination, the dose used in X-ray fluoroscopy and photography is very small, and it will be within a safe range, the radiation dose brought by a single film to the human body is equivalent to the amount of some of the amount that our human body takes in watching TV for an hour, and the dose of chest X-ray is equivalent to the number of times that of the film, that is to say, the damage caused by taking a chest X-ray is equivalent to smoking three cigarettes. Most of the CT room sites will have certain standard wall doors and windows built, which have a strong protection function.

Do you know how harmful it is to the human body to do a CT examination? The doctor gave an explanation, and you can't even think of it after reading it.

I believe many people know that CT is a very fast and accurate instrument, which not only saves time but also reduces the misdiagnosis rate of doctors. However, as soon as many people hear that CT is to be done, they think of the radiation and refuse directly. As everyone knows, many diseases can only be detected by CT.

Although CT is now more widely used in medical treatment, many people have to take CT regardless of the size of the disease, excessive use of this radiation will cause certain harm to the human body, there will be a potential risk of cancer, generally speaking, it should not be more than once a year.

Short-term low-dose radiation is not harmful to ordinary people, and people have a certain tolerance to radiation. CT and X-rays are not recommended during pregnancy!

Hello, the CT scan is done by X-ray. X-rays are damaging to the human body, and the more radiated radiation, the greater the risk of cancer.

Guidance: An occasional radiological examination will not cause damage to the body, and there is no need to worry too much, only long-term, high-dose, direct radiation will cause direct damage to the human body.

How much time interval should be between the second CT attempts?

X-rays are widely used, and more and more people are exposed to X-rays. Therefore, attention should be paid to the issue of protection in X-ray examination. It is necessary to understand the significance, methods and measures of radiation protection.

1. The significance of radiation protection X-ray penetration of the human body will produce certain biological effects. If the amount of X-rays exposed exceeds the allowable exposure, a radiological reaction may occur and even a certain degree of radiation damage. However, if the X-ray exposure is within the allowable range, it usually has little effect.

Therefore, there should be no doubts or fears about X-ray examination, but protection should be emphasized and valued, such as controlling the amount of exposure in X-ray examination and taking effective protective measures, using X-ray examination safely and reasonably, and avoiding unnecessary X-ray exposure as much as possible to protect the health of staff. In the past two or three decades, due to the improvement of X-ray equipment, the use of high-kilovolt technology, image enhancement technology, high-speed sensitization screen and fast X-ray photosensitive film, the amount of X-ray exposure has been significantly reduced, and the possibility of radiation damage has become less and less. However, this should not be taken lightly, with particular attention paid to pregnant women, children and workers who are exposed to radiation for a long time.

In recent years, interventional radiology has been carried out more and more, and the issue of radiation protection should be paid attention to. 2. Methods and measures of radiation protection In terms of technology, the principles of shielding protection and distance protection can be adopted. The former uses substances with higher atomic numbers, often lead or lead-containing substances, as a barrier to absorb unnecessary x-rays.

The latter uses the principle that the amount of X-ray exposure is inversely proportional to the square of the distance, and reduces the amount of exposure by increasing the distance between the X-ray source and the human body. There are two types of X-rays from the X-ray tube to the human body: primary emission lines and secondary emission lines, the latter occurs during the irradiation and penetration of other substances by the former, and its energy is smaller than that of the former, so it has a greater impact. X-ray tube shells, light shields and apertures, filter plates, lead glass behind the screen, lead screens, lead rubber aprons, lead gloves and walls are usually used for shielding protection.

Increasing the distance between the human body and the X-ray source for distance protection is a simple protective measure. On the patient side, in order to avoid unnecessary X-ray exposure and exposure exceeding the allowable amount, it is necessary to select the appropriate X-ray examination method and design the correct examination procedure. The number of exposures per x-ray should not be too high, and it is not advisable to repeat the tests multiple times in a short period of time (this is especially important for tomography and contrast tests).

When irrigating, attention should be paid to the accuracy of the location, range and exposure conditions. The adjacent gonads of the control field should be covered with a lead eraser. On the radiologist side:

Necessary protective measures should be formulated in accordance with the relevant national health standards for radiation protection, X-ray examination should be carried out correctly, health regulations should be carefully implemented, and the dose received by radiographers should be regularly monitored. Wear lead rubber aprons and lead gloves when seeing, and use the principle of distance protection to strengthen self-protection. In interventional radiology, unnecessary fluoroscopy and photography should be avoided.

Digital subtraction angiography (DSA) equipment, USG, and CT should be used for monitoring.

There is some damage, but it is not powerful enough to go. As long as it is not directly irradiated under X-rays, it is generally fine. You can usually go out and bask in the sun more often, which can repair some damage!

If you don't feel weak, mentally weak, and have a poor appetite, it's okay, and if you do, go to the hospital to have your white blood cells checked!
