What protects me from the radiation of computed tomography (CT) scans?

ANSWER

Your doctor should use the smallest possible dose of radiation to do the scan -- especially if you need to have several of them. Ask if the technician can shield the parts of your body that don’t need the test with a lead apron. This will block the X-rays from entering those areas.

Keep a record of the CT scans and other X-rays you have, so you'll know how much radiation you're getting. It will also prevent you from repeating a test you've already done.
