Japan's earthquake triggered the crisis of nuclear radiation. In fact, there are a lot of radiations existing in our life, such as the radiation of making a chest CT equals to 700 times of chest x-rays. Medical experts advise that medical examination should prevent excessive adverse effects on the body.

In life, many people feel that CT, radiography and other tests are harmless, so they can do these tests casually. In fact, these tests are harmful and can bring a permanent injury to patients. When people decide the programs of physical examination, they can choose X-ray to check diseases and there is no need to do CT. Only when the diseases cannot be confirmed, people could choose CT to do targeted check to avoid the increased radiation dose of X-ray.

Statistical data shows that the radiation amount of cardinal coronary artery CT is 700 times of chest x-ray. To many younger people who do not need to do CT check, especially to young women, it not only have no examination effect and waste medical funds, but also brings cancer risks to themselves.

CT is a kind of examination which applies the principle that ...
... x-ray could penetrate human tissue. X-ray is a kind of nuclear radiation, so it has damage to human tissue. Exposure to X-ray may cause cancer and other diseases. The more you exposed under x-ray, the greater risk of cancer it is. The research result of International Commission on Radiological Protection shows that in a city of about a 10 million population, there are nearly 350 people have cancer, leukemia or other genetic disease caused by X-irradiation.

Although the radiation dose and cancer risk of CT have no sufficient scientific data, the hospital should reduce CT radiation dose by updating the equipment, strictly control the indications for using CT to achieve the optimal principle: obtain valuable medical imaging with a minimum price and the smallest amount of radiation.
