Many people know that CT examination is radiation, and many people think that after the CT is done, there are radiation, and they must stay away from those who have done CT.Is this statement right?
The first half is correct. The CT examination is indeed radiation, which may be harmful to the body.Because CT examination is an X -ray examination, X -rays can cause ionizing radiation. Long -term large -dose contact radiation can cause damage to the body, cause damage, and even cancer.However, cancer will not be immediately manifested. It may take several years or even decades to increase the incidence of cancer, and it will definitely cause cancer. Instead, there is a certain probability.In a large relationship, the greater the dose, the greater the possibility of cancer.
Since CT may cause cell cancer, it cannot be done?Everyone thinks too much. Doing CT once or twice, the dosage accepts is very small, and the harm is not great.
In fact, we live on the earth, even if you do nothing, there will be radiation.Moreover, it is radiating every day to receive radiation, smoking, and airplanes every day.As long as the dose does not exceed the standard, the harm to the body is very small, you can rest assured.
In 2012, the Ministry of Health of China announced the new version of the "GBZ165-2012 X-ray computer tomography radiation protection requirements", and for the first time announced the level of diagnosis reference for different people and CT inspections of different parties and parts.The dosage limit of the radiation staff is 50 MSV each year. The average radiation upper limit accepted per year within five years is 20 MSV, that is, as long as the total radiation amount of acceptance is controlled to the safe value, it is safe!
However, if you want to be pregnant or have been pregnant, you must tell your doctor that it is best not to do CT examination, especially women in the early pregnancy.If you want to get pregnant, women do not do CT or X -rays within three months within half a year.
