People are sometimes exposed to x-ray radiation during the production process. If the protective measures against radiation are not appropriate and the operation rules of the equipment are violated, the dose value of the radiation received by the human body exceeds a certain limit, which will do harm to the human body. Under the x-ray radiation, the damage of human depends on the type of x-ray radiation, the dose value, the irradiation conditions, and the sensitivity of the human body. x-ray radiation can cause radiation diseases. It is a systemic response to the human body. All organs and various systems will undergo pathological changes, but the most obvious one is the changes in the nervous system, hematopoietic organs, and digestive system.
The damage to the human body caused by x-ray radiation can be divided into acute and chronic radiation damage. Receiving a certain dose of radiation in a short period can cause acute injury to the human body. It is usually seen in nuclear accidents and radiotherapy in the medical field. Dispersing a certain dose of radiation for a long time can cause chronic radiation damage, such as skin damage, hematopoietic dysfunction, reduced white blood cell count, and impaired fertility. Besides, excessive radiation can also cause cancer and cause fetal death and deformity.
Three principles of protection
(1) Time protection: No matter what kind of radiation, the cumulative dose of human exposure is proportional to the exposure time. The longer the exposure to radiation, the more serious the radiation hazard. Try to shorten the working hours under radioactivity which to reduce the exposure dose.
(2) Distance protection: The radiation dose value in a place is inversely proportional to the distance from the radiation source. The greater the distance from the radiation source, the smaller is the dose value. Keep away from radioactive sources as much as possible in daily work.
(3) Shielding protection: Set up protection barriers between people and ray sources. Because x-rays pass through a material with a large atomic number, the x-rays will be absorbed to a certain extent, so that the radiation dose to the human body is reduced. Commonly used shielding materials include lead (or other heavy metals), reinforced cement, lead glass, etc.
The biggest concern about x-ray radiation comes from the fact that it may cause fatal diseases to people who are exposed to radiation, as well as genetic defects in their offspring. The possibility of such performance depends on the dose value of the radiation received by the person, regardless of whether the exposure comes from a natural radiation source or an artificial radiation source. With the deepening of people's research on x-ray radiation in recent ten years, more and more understanding of the effects of x-ray radiation. People have developed radiation protection methods to protect humans from various radiation sources. Even so, people still have concerns about radiation.
Radiation is one of the causes of many malignant diseases. The radiation is invisible and intangible, making this hazard even more frightening. Whenever people think of accidents that have occurred in nuclear power plants and other facilities, they are still working in some cases today. People tend to associate these forms of radiation with the "nuclear" including nuclear weapons, making people even more worried.
Another reason that people areworried about radiation may be related to the lack of reliable and easily obtained information and the resulting misunderstandings. Therefore, people need to learn more about radiation safety knowledge, and must have a understanding of the protective measures of x-ray radiation equipment in advance. Seeing that there are improper protection situations, it is necessary to put forward suggestions for improvement and urge relevant personnel to deal with them on time.
X-ray radiation is not terrible, the terrible thing is people lack of knowledge about radiation safety.
