Which of the hospital's examination instruments are radioactive?

Some of the instruments used in hospitals are radioactive, such as X-rays, CTs, ultrasounds, and MRIs. If you pay attention, when you go to the hospital for checkups there are usually some friendly reminders or something like that posted outside the room where these checkups are done.

CT examination of the radiation dose will be higher,

every time you go to the hospital for examination, in the examination room of the door will be posted, there is radiation, please do not bring the cell phone in and so on the text. Every time you walk through the door from the CT room, will be very fast walk through, remember before someone told me, when the CT room lights are in the working state, this time there is radiation, when the state of the extinguished, is to prove that there is no radiation, this time you can quickly pass. I don't know if there is any truth in what he said, but every time I walk through the door of the CT room, I always run through quickly.

?Radiation from X-rays is the lowest equivalent of safety

Basically all instruments used in hospitals for examinations have radiation, which is divided into two types: electromagnetic radiation and ionizing radiation. Our bodies also experience radiation every day at home, just more and less, and as long as it's within the realm of a correct amount, the body won't be affected in any major way. Many of us have probably had an X-ray, which is in the hospital, and of all the tests the radiation is the lowest, equivalent to the safe value. Every time we go for a checkup we will find that very soon the doctor will say the checkup is finished, come down, and then the light goes off, that is, the moment the X-ray touches your body, our body will have some radiation, and the rest will be nothing.

?Ultrasound and magnetic **** vibration and so on, there will be some radiation, as long as we pay attention to the number of checkups, especially the CT film, do not go many times to the CT film, the radiation of our body will not be too big a problem. Now the body health check, must be through these instruments, if there is no such instrument, the doctor can not be very good to give you judgment, so you must rely on these medical equipment, not too frequent to do these tests, there is no big problem.
