Now the fashion for computer tomograms has gone. People even manage to buy a test without a doctor's prescription. Those who are especially concerned do it many times.
It seems that not everyone has heard of radiation. Even if you and I do not receive X-rays and fly on airplanes, we will still pick up a certain dose of radiation in a year just at ground level. We live with it. But each tomogram of the chest organs adds radiation to us in three years of ordinary life at ground level.
Even 10 years ago, Americans calculated that in the near future, about 1 - 2% of all malignant neoplasms will develop precisely from an X-ray examination.
Some organs are more sensitive to radiation. These are the esophagus, chest, bladder. Others, which are more resistant, are the pancreas, rectum, and prostate.
The American Association of Physicists who work in the field of medicine believes that there is no need to panic, because death from purely theoretically, cancer can only result from a single dose of radiation of 50 millisieverts, or if you gradually accumulate 100 millisieverts.
Sievert is a unit of absorbed radiation per kilogram of our native meat. That is, we are not talking about a brick that has been exposed to radiation, but about living tissue.
So in the same publications where these encouraging figures are written, there is also a list of procedures that give radiation. If we take only a computed tomography of the chest organs from there, then it can scald our chest, along with all the organs located in it, with a dose of 4 to 18 millisieverts.
Well, that is, if you show off and take the worst option, then six CT scans of the chest organs can kill you due to the development of a fatal malignant tumor. And this is taking into account the fact that those physicists are very fond of radiation and are not too afraid of it. Have you counted what dose you have already taken?
Further more interesting. If you have done several CT scans in a short period of time, then this will no longer be a single dose and not an accumulated dose. This will be a very quickly received dose. It is worse than accumulated.
For heaven's sake, don't do extra CT scans without a doctor's prescription. Don't ask your doctor for extra CT scans. Last winter, the Chinese did a lot of CT scans, but they didn't get any additional benefit in treating covid. In most cases, a conventional X-ray could be enough.
