Is X-ray harmful to health?

1.x-rays have certain killing and destroying effects on biological cells. Excessive X-rays will affect physiological functions, cause chromosomal abnormalities and lead to cancer. But proper irradiation will not affect human health. Because the dose used by medical staff for X-ray fluoroscopy and photography is very small, only within the safe dose. In particular, occasional chest x-ray, gastrointestinal examination, bone X-ray or angiography will not cause adverse reactions. Moreover, the X dose used for filming is not completely absorbed by people, most of it penetrates the human body, and only a small part is absorbed by the human body. If we want to say a specific value, it is that the human body really absorbs only a few tenths or even less of the dose used.

Moreover, the radiation inspection equipment used in major hospitals has long been replaced by digital radiography (CR) and direct digital imaging (DR), and the radiation amount has been greatly reduced, accounting for only the original 1/7.
