Q & A

Who is the presenter of the video, and what is their background?

The presenter is Muhammad Amirul Mustofa, a student of Electrical Engineering at Islamic University of Balitar, class of 2017.

What significant discovery related to X-rays did Wilhelm Conrad Röntgen make?

Wilhelm Conrad Röntgen discovered X-rays on November 8, 1895, accidentally producing an image from a cathode ray generator.

What are the main components of an X-ray machine?

An X-ray machine consists of a source or generator of X-rays and a detection system, which can be film or digital technology.

What is the working principle of an X-ray machine?

X-ray machines generate X-rays by accelerating electrons from a heated cathode toward a target anode, where the interaction creates X-rays and heat.

How is an X-ray tube constructed, and what is its function?

An X-ray tube is a vacuum-sealed device containing a negatively charged cathode and a positively charged anode. It functions to produce X-rays when electrons emitted from the cathode collide with the anode.

What percentage of energy from the interaction of electrons with the anode is converted into X-rays?

Approximately 1% of the energy from the interaction is converted into X-rays, while about 99% is converted into heat.

What role do X-rays play in healthcare?

X-rays are used to visualize the internal structures of the body, especially bones, aiding in medical diagnoses and treatments such as radiotherapy for cancer.

What is radiotherapy, and how do X-rays contribute to this treatment?

Radiotherapy is a cancer treatment that uses high-energy X-rays to kill harmful cells in the body, effectively targeting tumors.

Besides healthcare, what are some other applications of X-ray technology?

X-ray technology is also used in security screenings at airports, industrial applications, and in fields like astronomy.

What are the advantages of using X-rays in dental applications?

X-rays are particularly useful in dentistry because they can penetrate soft tissue while being absorbed by denser structures like bones and teeth, allowing for detailed imaging.
