Nowadays, people in China still do not know enough about the “double-edged sword” of radiation, and some even “like” to take films …… It is known that CT and X-ray are cheap and fast tests. It is still very convenient and effective to use in emergency or urgent cases, but now the consequences of unrestricted application are very frightening. This is caused by the lack of awareness of the double-edged sword of radiation in China (in foreign countries, it is quite “difficult” to do a general X-ray examination, and you need to sign a series of informed consent forms and conduct a lot of assessments to see if you need to do it). Therefore, as medical professionals and patients, we hope that our countrymen will have a proper and objective understanding and reasonable application.
