What should I pay attention to when taking a chest X-ray?
X-rays penetrating the human body will have certain biological effects. If the amount of X-rays exposed is too much, which exceeds the allowable radiation amount, it may cause radiation reaction and even a certain degree of radiation damage. However, if the X-ray radiation is within the allowable range, the impact is generally small. In recent ten years, due to the improvement of X-ray equipment, the use of high kilovolt technology, image enhancement technology, high-speed intensifying screen and fast X-ray photographic film, X-ray radiation has been obviously reduced, and the possibility of radiation damage is getting smaller and smaller.
Chest X-ray examination has the largest radiation, and one chest X-ray examination is equivalent to taking 10 X-rays. However, chest X-ray examination usually takes tens of seconds, so the harm to human body is very limited. An adult's chest X-ray has almost no obvious harm.
What can you see from the X-ray?
