When it comes to the word radiation, many people will tremble in their hearts, thinking that radiation is an invisible killer that eats away at our physical health unconsciously.
However, radiation is ubiquitous in our lives, whether it is mobile phones and computers used in daily life, or various instruments used in hospital examinations, a certain amount of radiation will be generated.
So is radiation so scary?Which of the X-rays, ultrasounds, CT and other examinations that are often used in daily life is more harmful?A popular science!
1. Is radiation so scary?
To understand the dangers of radiation, the first thing we need to do is to have a comprehensive understanding of it. From a clinical point of view, there are two types of radiation, the first type is ionizing radiation and the second type is non-ionizing radiation.
What we usually call radiation is actually ionizing radiation, which is the use of sufficient energy to ionize atoms or molecules. For example, X-ray inspection, which is used in medical testing, can affect the health of the examiner if not done properly.
The energy of non-ionizing radiation is relatively weak and usually does not bring harm to the body, such as the radiation generated by mobile phones and computers.
So we can see that the harm of radiation is not as serious as we think. Under normal circumstances, only some medical mispractices can cause radiation effects. So we should not be very worried about radiation anymore, we must face it correctly and use it.
2. The hazards of B-ultrasound, X-ray and CT examination.
When discussing the dangers of ultrasound, X-ray, and CT examinations, we must first understand how these examinations work.
1.B-ultrasound.
There is no radiation in ultrasound examination, because the principle of examination is to use ultrasound waves to penetrate the human body, and the sound waves encounter different tissues to produce reflected waves, thus forming images. Doctors can use these images to determine the condition of the lesion, so you don't have to worry about it when you do ultrasound.
2.X-ray.
X-rays have a certain amount of radiation, but the overall radiation dose is relatively small. Under normal circumstances, a chest x-ray absorbs about 01 mSv is only 1,2000 of the maximum dose that the human body can withstand at a time.
Therefore, there will be no harm to oneself through one X-ray examination, but be careful not to perform multiple examinations in large doses.
3.CTCT itself also has a certain amount of radiation, and compared with X-rays, its radiation dose is relatively high. The amount of radiation generated varies depending on the CT machine and for different scanning sites and the clarity of the image.
But even so, there is no need to worry too much about this, because when medical technology continues to improve, it is possible to adjust the X-ray data of CT equipment, and as long as it is not a large dose of multiple examinations, there is no need to prioritize radiation.
In general, in B-ultrasound X-ray and CT examination, B-ultrasound does not produce any radiation, and it uses the principle of ultrasound to examine the lesion. X-rays and CT both produce a certain amount of radiation, with the former having less radiation and the latter having a higher amount of radiation.
But no matter what kind of examination it is, it is to help us better determine that as long as it is operated properly, it will not cause serious damage to your health, so you can rest assured that you can accept the examination under the guidance of a doctor.
