If you require seven head CT scans, the more dangerous option would be not to have them. Although CT scans do expose you to a small amount of radiation, your doctor/consultant has clearly decided that the benefits from these scans will far outweigh the risks.

Supposedly having one chest x-ray exposes you to the same amount of radiation as a 2 hour aeroplane flight. So seven head CT scans will be the equivalent of doing a few long-haul flights. Even so, no-one ever gets radiation side-effects from long-haul flights.
