X-ray & Gamma rays

Cards (21)

  • What are the two types of rays discussed in the video?
    X-rays and gamma rays
  • What is the primary characteristic of x-rays and gamma rays compared to other electromagnetic waves?
    They have the shortest wavelength and the highest frequency
  • What is the main use of x-rays?
    To help view the internal structure of objects, including the human body
  • How does a typical x-ray machine work?
    It fires x-rays through a person's body and records the ones that get through using a detector plate
  • Why do x-rays get absorbed by dense materials like bones?
    Because dense materials absorb more x-rays than less dense materials
  • What happens to x-ray images based on the density of the material?
    Dense areas like bone appear white, while less dense areas appear black or gray
  • What are x-rays commonly used to detect?
    Broken bones and other diseases
  • What is the risk associated with x-ray exposure for patients?
    They receive a small amount of radiation, which can be harmful
  • Why do medical staff wear lead aprons during x-ray procedures?
    To protect themselves from x-ray exposure
  • What is one of the uses of gamma rays in medicine?
    They can be used in medical imaging and to treat cancer
  • What is the focus of this video regarding gamma rays?
    How gamma rays can be used to sterilize medical equipment and food
  • Why are gamma rays effective for sterilization?
    They can kill microorganisms without causing damage to the materials
  • What is an alternative method to gamma rays for sterilizing medical equipment?
    Boiling water
  • What is a limitation of using boiling water for sterilization?
    It can damage materials like plastic that may melt
  • How do gamma rays affect food during sterilization?
    They kill harmful microbes without altering the food
  • What is the benefit of using gamma rays for food preservation?
    It keeps food fresh for longer by killing microorganisms
  • What must be considered when using x-rays and gamma rays in medicine?
    The trade-off between their benefits and the risks of ionizing radiation
  • What is a potential consequence of ionizing radiation from x-rays and gamma rays?
    It can damage cells and potentially lead to cancer
  • Why is it often worth the risk to use x-rays and gamma rays in medical settings?
    They help diagnose and treat diseases effectively
  • What are the uses of gamma rays in medicine?
    • Medical imaging
    • Treatment of cancer (radiotherapy)
    • Sterilization of medical equipment
    • Sterilization of food
  • What are the pros and cons of using x-rays and gamma rays in medicine?
    Pros:
    • Help diagnose diseases
    • Aid in treatment of conditions

    Cons:
    • Can damage cells
    • Potential risk of cancer
