Gamma RAYS

By Genaro Anaya/ Period 3

Description of Gamma Rays

  • The Wavelength Range of gamma rays is <1 (nm)
  • The Frequency of Range of gamma rays is > 3 × 10

    19 (Hz)

  • In a vacuum all light travels the same speed no matter what the wavelength/frequency. Gamma radiation rays have a smaller wavelength and larger frequency.

  • Gamma rays can be used to treat cancer, and gamma ray bursts are studied by astronomers.

  • Gamma Rays are a form of electromagnetic radiation.

Everyday Applications

Two applications about this wave are the radiotherapy which is a machine used by doctors to kill cancer cells with out doing any surgery to the patient. Another thing gamma rays are used for are to kill microbes, and are used to sterilise food so that it will keep fresh for longer.
This is known as "irradiated" food.

Health impacts

  • gamma radiation is ionizing radiation, meaning that it is sufficiently energetic to break bonds in genetic material, structural components of cells and other biological molecules.
  • symptoms of mild radiation poisoning from gamma rays include nausea and vomiting, progressing to generalized weakness and fatigue several weeks later.
  • More bad affects may include diarrhea, headache, hair loss, skin burns and poor healing,

Video Summary

The video explains and gives a very good understanding of what are gamma rays. Like gamma rays are the highest form of light and the most energetic form of light. And the only thing that can generate gamma rays are stars exploding in space with very strong magnetic fields.
