a) State one other use of X-rays. One other use of X-rays is for security screening, such as in airport baggage scanners to detect hidden objects. Other uses include industrial inspection (e.g., checking for cracks in materials) or radiotherapy for cancer treatment. b) Describe how X-rays create images of the internal structures. Step 1: X-rays are directed through the body. As they pass through, different tissues and structures absorb the X-rays to varying degrees. Step 2: Denser materials, such as bones, absorb a significant amount of X-rays, preventing them from passing through. Less dense tissues, like muscles and organs, absorb fewer X-rays. Step 3: The X-rays that successfully pass through the body are then detected by a photographic film or a digital sensor on the other side. Step 4: The areas where more X-rays were absorbed (e.g., bones) appear lighter or white on the resulting image, while areas where X-rays passed through easily (e.g., soft tissues, air) appear darker or black. This difference in absorption creates a contrast, forming an image of the internal structures.

Step-by-step solution

Part a

Part b· 4 steps

X-rays are directed through the body.

Denser materials, such as bones, absorb a significant amount of X-rays, preventing them from passing through.

The X-rays that successfully pass through the body are then detected by a photographic film or a digital sensor on the other side.

The areas where more X-rays were absorbed (e.g., bones) appear lighter or white on the resulting image, while areas where X-rays passed through easily (e.g., soft tissues, air) appear darker or black.
