Engaged in medical imaging, the human body is a certain amount of radiation. Especially girls, but now there have been many measures to prevent radiation. If you are engaged in medical imaging for a long time, the body to eat the radiation is more, in this case, should the unit will equip you with precautions, and the country will also have a vacation.
Medical imaging is harmful to the body
Harmful. X-rays irradiated to the biological organism, the biological cells can be inhibited, destroyed or even necrotic, resulting in the organism to varying degrees of physiology, pathology and biochemistry and other aspects of the changes. Different biological cells have different sensitivities to X-rays, which can be used to treat certain human diseases, especially tumors. In the use of X-rays at the same time, people have found to lead to patient hair loss, skin burns, staff vision disorders, leukemia and other radiation damage in the application of X-rays at the same time, but also should pay attention to its harm to the normal organism, pay attention to take protective measures.
At present, the average person in life can be exposed to ionizing radiation mainly from medical radiation, which X-ray examination of the radiation released, is the non-professionals may be exposed to the main source of ionizing radiation. Pregnant women need to focus on preventing radiation, especially ionizing radiation, the reason is that ionizing radiation has a high energy and can ionize human molecules, which may cause damage to the cells of the fetus that has not yet developed, causing stillbirth or malformation.
The effect of girls enrolled in medical imaging on the body
Instruments operated by medical imaging, mainly including X-ray imaging instruments, CT (ordinary CT, spiral CT), positron scanning (PET), ultrasound (divided into B ultrasound, color Doppler ultrasound, cardiac ultrasound, three-dimensional color ultrasound), magnetic **** vibratory imaging (MRI), electrocardiogram instruments, electroencephalography instruments, and so on.
Some of the above instruments are not harmful, such as ultrasound, which can also be given to pregnant women and is basically harmless.
Some of these instruments produce radiation, which is harmful to the human body, but to cause harm to the human body must also reach a certain dose. Such as radiology have general release CT and magnetic **** vibration will produce radiation. But the operation of the general technician to operate the equipment, the physician based on the results of the diagnosis. This process the technician will operate and contact with the instrument, but during the exposure, the machine and the technician is not in a room. Nowadays, if the conditions of the hospital are not particularly poor, the protection facilities will meet the standard, the equipment produced by the radiation on the operation of the equipment of the technician almost no effect, and the physician in the process does not even need to touch the equipment, can be completely away from the source of radiation, only need to give a diagnosis of the photographs of the child on the results.
