Yes, it can. As you know mutations are changes of
the DNA in our cells. Radiation is a type of
high-energy wave that can damage the DNA in our
cells. Another student asked me about this a
couple of weeks ago and I'll tell you some of what
I told her. Cells that are dividing are the most
likely to be hurt by radiation. Every time cells
divide, their DNA has to be copied and divided
equally into the new cells.
The lining of
our gut is being constantly replaced. Our brain
cells almost never divide. Why do you think some
cells divide more than others?
