How to take an x-ray with a mobile phone? You can see the bones.

It is out of the question. Mobile phone cameras don't have the penetrating power of X-rays. It's completely false and unreliable.

The application of X-ray in medical diagnosis is mainly based on its penetrability, differential absorption, photosensitivity and fluorescence. Because X-rays will be absorbed in different degrees when passing through the human body, for example, the amount of X-rays absorbed by bones is more than that absorbed by muscles, so the amount of X-rays after passing through the human body is also different.

In this way, it carries the information of the density distribution of various parts of the human body, and the intensity of fluorescence or photosensitive effect caused on the fluorescent screen or photosensitive film is very different, so shadows with different densities (after development and fixing) will be displayed on the fluorescent screen or photosensitive film. According to the contrast between light and dark, combined with clinical manifestations, laboratory examination results and pathological diagnosis, we can judge whether a certain part of the human body is normal or not.

Hazards of x-rays

1, X-rays have certain killing and damaging effects on biological cells. Overexposure to X-rays will affect physiological functions, cause chromosomal abnormalities and lead to cancer.

2. X-ray will cause genetic variation of cells and increase the risk of cancer or infertility. Therefore, when doing X-ray chest X-ray examination, at least the gonadal organs should be protected.

3. According to the medical calculation, when a healthy woman receives fluoroscopy, each breast absorbs at least 1000 millirem of radiation, which means that the probability of breast cancer will increase 1%.

4. In X-ray examination, the radiation amount of chest radiograph is the largest, and the radiation amount of one chest radiograph is equivalent to the total amount of 10 chest radiograph. If you receive multiple X-rays in a short period of time, it will cause serious damage to body cells, decrease immunity and greatly increase the probability of inducing cancer diseases.
