X-rays are a form of electromagnetic radiation that have the ability to pass through various types of matter, including human flesh, relatively easily. This penetrative property is what makes them particularly useful in medical imaging, such as X-ray imaging of bones and internal organs. Since soft tissues contain a high concentration of water, they are less dense than bone, allowing X-rays to pass through them more readily while being absorbed by denser materials like bone. This differential absorption creates the contrast that enables the visualization of structures within the body.

The other choices do not accurately describe X-rays. While X-rays are indeed utilized for various purposes, cooking is not one of them; microwave radiation is more commonly used for cooking. Furthermore, it is important to note that X-rays can be harmful in sufficient doses, which means they should be used judiciously rather than being considered harmless in any amount. Lastly, not all materials absorb X-rays equally; for instance, air has very low absorption, whereas metals can absorb X-rays significantly. Thus, the key feature is their ability to pass through flesh easily, providing the foundation for their application in medical imaging.
