No, but it can harm your cells.


No. Radiation travels through the body from source to detector.

Hello,

You are asking an important question. Does radiation from a ct scan stay in your body? The short answer is no.

Radiographic exams are tests that a doctor needs to evaluate symptoms. These tests serve to visualize parts of the body that are otherwise not able to be seen. Low safe doses of radiation are used for this purpose. Some nuclear medicine tests may have some remaining radiation for a short time.
The dose from CT scan is very low compared to the dose that we give to treat cancer, and this dose doesn't stay in your body.
