China's regulations allow staff to x-ray dose: 1000 microsieverts?
The dose of radiation is expressed in millisieverts or microsieverts, with 1 millisievert equaling 1,000 microsieverts.
Radiation may bring harm to the human skeletal system, reproductive system, blood system, etc. Patients who have been exposed to radiation need to go to the hospital in a timely manner and under the guidance of the doctor for relevant treatment so that radiation will not continue to cause harm to the human body.
1, the skeletal system: when radiation exposure to the human skeletal system for a long time, can constitute the human skeleton bone damage, may destroy bone cell proliferation, affecting the normal growth and development of bones, and in severe cases can cause bone deformities;
2, the reproductive system: long-term exposure to radiation, can cause damage to the human reproductive system, such as long-term exposure to radiation. May damage the chromosomes in the sperm or egg, which may lead to fetal development malformation, miscarriage, etc., can also lead to sperm development abnormalities, and even weak spermatogenesis, oligospermia, etc.;
3, the blood system: the body's hematopoietic stem cells are located mainly in the bone marrow, if the patient's skeleton is exposed to radiation for a long period of time, it may have an impact on the hematopoietic stem cells, inhibit hematopoietic differentiation of the stem cells, which may lead to anemia, Platelet reduction, and even increase the chances of leukemia;
4, other injuries: the human eye for a long time when exposed to radiation, may directly harm the retina, and once the human retina is damaged, there may be a loss of vision, there may be macular degeneration, which may cause blindness in severe cases. Radiation can also cause damage to human organs, such as the atrium, the lobes of the lungs and other organs, may be radiation damage, causing a decline in heart function, lung function abnormalities.
