Do X-rays penetrate through the skull?

Yes, X-rays can penetrate the skull, but the amount of penetration depends on the energy of the X-ray photons. The skull is a thick bone structure that can block or absorb some of the X-ray radiation, especially lower energy X-rays. However, higher energy X-rays, such as those used for medical imaging, can pass through the skull and provide images of the brain and other structures within.

During medical X-ray examinations of the skull or brain, the appropriate energy level is selected to ensure sufficient penetration while minimizing unnecessary radiation exposure. This is essential for obtaining clear and diagnostically useful X-ray images of the internal structures of the head.

It's worth noting that some substances and materials can affect X-ray penetration. For instance, metal objects, such as dental fillings or implants, may create artifacts or interfere with X-ray imaging. This is why patients are often required to remove certain metal objects before undergoing X-ray examinations of the head.
