Let's briefly introduce how long the radiation of filming has disappeared.

How long did the filming radiation disappear?

1, first of all, these rays can't be excreted and metabolized, but if they affect the body, they will generally damage chromosomes, and the genes of the body have various repair mechanisms, and the exact time is hard to say, but as long as they are not exposed to ct and X-rays frequently, they will generally not have any impact on the body.

2. If SPECT\CT and PET\CT films of nuclear medicine department are taken, a small amount of radioactive sources will be injected before filming. After filming, the body still carries radioactive sources, which are radioactive.

3. The half-life is different according to the injected drug radionuclide. Generally, 10 can be ignored after half-life. If you shoot this kind of film, avoid contact with pregnant women and infants when you go back.
