- hwillis 10y agoSource? Because I'm pretty sure that's completely untrue. Nervous tissue like the brain is the most resistant to radiation of any cell types in the body. Radiation affects faster growing cells the most, and nerve cells grow the slowest of any in the body. The brain is also the best shielded part of the body against x-rays, and the x-rays in a CT machine are necessarily highly collated, so unless your brain is getting scanned your brain is receiving almost zero dose. If CT scans damaged the body, it would be visible in the lymphatic and immune system first, and way before any other systems.
