How harmful are X-rays to the human body?

When we go to the hospital for a physical examination, the doctor sometimes asks us to take "X-rays". Regarding this invisible "X-ray", many people have such worries: "Will it damage my health?" The answer is no.

"X-ray" is called x-ray in medicine and is widely used in the diagnosis and treatment of diseases related to the digestive system, cardiovascular system and skeletal system. It does have a certain killing and damaging effect on biological cells, so when the human body is exposed to x-rays, it will produce certain physiological reactions. Excessive exposure for a long time can cause tissue damage, affect physiological functions, and even cause life-threatening consequences. However, the dose of X-rays used for disease examination is very small and strictly limited to safe doses. Doctors may also consider extending the interval between examinations if they need to perform repeated fluoroscopy on the patient. Normal people will occasionally have a chest X-ray or gastrointestinal examination, a bone X-ray or an angiogram, 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.
