Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Radiography?1895
2. What is the discoverer?Wilhelm Conrad Röntgen
3. What is the primary mechanism?Differential absorption of X-rays by matter
4. What is radiography and how does it work?Radiography is a way to see inside objects using X-rays. X-rays are made when fast electrons hit a metal target inside a special tube. The X-rays pass through the body and are captured on film or a digital screen to make an image.
5. Why do bones show up brighter on X-ray pictures?Bones contain a lot of calcium, which stops more X-rays than soft tissues. Because they block more X-rays, they appear white or bright on the picture, while softer parts look darker.

Bremsstrahlung: Radiation produced when a charged particle is decelerated by another charged particle.
Attenuation: The reduction in the intensity of a radiation beam as it passes through a material.
Digital Radiography (DR): A system that uses electronic detectors to capture X-ray images directly as digital data.
Non-Destructive Testing (NDT): Methods used to evaluate the properties of a material, component, or system without causing damage.
