What harm does X-ray radiation do to human body?

When we go to the hospital for a physical examination, the doctor sometimes asks us to take an "X-ray". Many people are worried about this invisible "X-ray": "Will it harm my health?" The answer is no.

"X-ray" is called X-ray in medicine, which is widely used in the diagnosis and treatment of diseases related to digestive system, cardiovascular system and skeletal system. It does have a certain destructive effect on biological cells, so the human body will have a certain physiological reaction after being irradiated by X-rays. If it is overexposed for a long time, it will cause tissue damage, affect physiological functions and even cause life-threatening. However, the X-ray dose used for disease examination is very small, strictly speaking, it is within the safe dose. If the doctor needs to repeatedly fluoroscope the patient, he will also consider extending the examination interval. Normal people occasionally have a chest film or gastrointestinal examination, a bone X-ray film or angiography, and there will be no adverse reactions. Therefore, taking "X-rays" in the hospital is safe and will not cause any harm to the human body.
