How much does a CT scan affect a person?

CT is computed tomography, which uses precisely collimated x-rays, Y-rays, and ultrasound, along with a highly sensitive detector, to scan around a part of the body, one section at a time. It sounds very specialized, and also very scary, because it is equivalent to the human organs into a piece of a careful observation and, radiation radiation really can not be underestimated ah. This is why so many people are scared of CT. So how much damage can a CT do to a person?

First:Ionizing radiation.

The main source of harm from CT is the ionizing radiation produced by X-rays. In small doses cells do not die, but they become abnormal, some temporarily and some permanently. A large dose of radiation can cause acute radiation sickness, such as massive hemorrhage, bacterial infection, anemia, endocrine disruption, and DNA mutation. In fact, a CT dose is small, but to some extent it may also cause changes in the macromolecular structure of cells and damage cells.

Second:The possibility of cancer increases.

CT is essentially an x-ray machine, which may alter the macromolecular structure of the body, causing changes in the cells, with the serious consequence of making the cells cancerous. While it's unlikely that one or two CT scans would cause this result, it does raise a person's chances of getting cancer.

While it's true that CT can be harmful to people, it's not as bad as you might think, all research that isn't dose-driven is hooliganism, and as long as one isn't dealing with radioactive substances all the time, as Madame Curie was, it's unlikely that the bone marrow suppression (obstructive anemia) that Madame Curie suffered from would be something that she would get.
