What is a common source of gamma radiation?
They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes. On Earth, gamma waves are generated by nuclear explosions, lightning, and the less dramatic activity of radioactive decay.
What are the four sources of gamma rays?
Gamma rays are produced primarily by four different nuclear reactions: fusion, fission, alpha decay and gamma decay. Nuclear fusion is the reaction that powers the sun and stars.
What is a natural source of gamma rays?
Gamma radiation is released from many of the radioisotopes found in the natural radiation decay series of uranium, thorium and actinium as well as being emitted by the naturally occurring radioisotopes potassium-40 and carbon-14. These are found in all rocks and soil and even in our food and water.
What is an example of gamma radiation?
High-energy photons occur in nature that are known to be produced by processes other than nuclear decay but are still referred to as gamma radiation. An example is “gamma rays” from lightning discharges at 10 to 20 MeV, and known to be produced by the bremsstrahlung mechanism.
What can gamma rays be stopped by?
Gamma rays are a radiation hazard for the entire body. They can easily penetrate barriers that can stop alpha and beta particles, such as skin and clothing. Gamma rays have so much penetrating power that several inches of a dense material like lead, or even a few feet of concrete may be required to stop them.
What are 4 types of radiation from the sun?
Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
What are 3 uses for gamma rays?
Uses of Gamma Rays:
- Sterilize medical equipment.
- Sterilize food (irradiated food)
- Used as tracers in medicine.
- Radio Therapy- In oncology, to kill cancerous cells.
- Gamma-Ray Astronomy.
What are 5 uses of gamma rays?
Do we use gamma rays?
Gamma rays are ionizing electromagnetic radiation, obtained by the decay of an atomic nucleus. Gamma rays are used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry.
