X Rays – Class 12 | Chapter – 8 | Physics Short Notes Series PDF for NEET & JEE

X Rays: X-rays are a type of electromagnetic radiation that has a shorter wavelength and higher energy than visible light. They were discovered in 1895 by Wilhelm Conrad Röntgen and have since been widely used in many different applications. X Rays have revolutionized medical imaging and have many other important applications in industry, security, and science. However, due to their high energy and potential for causing biological damage, exposure to X Rays must be carefully controlled and monitored.

Properties of X Rays

Properties of X rays are:

  • Wavelength: X-rays have a wavelength between 0.01 and 10 nanometers, which is shorter than that of ultraviolet rays.
  • Energy: X-rays have a high amount of energy due to their short wavelength.
  • Penetration: X-rays can penetrate through many materials, including soft tissues and bones in the human body.
  • Ionizing radiation: X-rays are ionizing radiation, meaning they can ionize atoms and molecules, which can lead to damage to biological tissues.
  • Medical imaging: X-rays are commonly used in medical imaging to produce images of internal structures of the body. X-ray machines produce a beam of X-rays that is directed through the body, and the X-rays that pass through the body are detected and used to create an image.
  • Industrial imaging: X-rays are also used in industrial imaging to inspect structures, such as welds and pipes, for defects or damage.
  • Radiation therapy: X-rays are used in radiation therapy to treat cancer by killing cancer cells.
  • Security scanning: X-rays are used in airport security scanners to detect objects that may be hidden on a person or in their luggage.
  • Material analysis: X-rays can be used to analyze the structure and composition of materials, such as crystals and alloys.
  • Astronomy: X-rays are also used in astronomy to study high-energy phenomena, such as black holes and neutron stars.

Applications of X Rays

X-rays have numerous applications in different fields due to their ability to penetrate through materials, including human tissue and bones. Some of the major applications of X Rays include:

  • Medical imaging: X-rays are widely used in medical imaging to produce images of the internal structures of the body. X-ray machines produce a beam of X-rays that is directed through the body, and the X-rays that pass through the body are detected and used to create an image. This can help doctors diagnose and treat a variety of medical conditions.
  • Radiation therapy: X-rays are used in radiation therapy to treat cancer by killing cancer cells. In this treatment, a beam of high-energy X-rays is directed at the cancerous area, and the X-rays damage the DNA of the cancer cells, causing them to die.
  • Industrial imaging: X-rays are used in industrial imaging to inspect structures, such as welds and pipes, for defects or damage. This can help prevent accidents and ensure the safety and reliability of industrial equipment.
  • Security scanning: X-rays are used in airport security scanners to detect objects that may be hidden on a person or in their luggage. These scanners produce a low-dose X-ray that can penetrate through clothing and other materials, but not through human tissue.
  • Material analysis: X-rays can be used to analyze the structure and composition of materials, such as crystals and alloys. This can help researchers better understand the properties of materials and how they can be used in different applications.
  • Astronomical imaging: X-rays are used in astronomy to study high-energy phenomena, such as black holes and neutron stars. X-ray telescopes are used to detect and study the X-rays emitted by these objects, which can provide important insights into the nature of the universe.
