Description Of A Gamma Ray

It is a photon of penetrating electromagnetic radiation (gamma radiation).

Wavelength Range: less than 10 m

Frequency Range: greater than 10^19 Hz

Velocity In A Vacuum: 300,000,000 m/s

Gamma radiation, also known as gamma rays, and denoted by the Greek letter γ, refers to electromagnetic radiation of an extremely high frequency and therefore consists of high-energy photons. Gamma rays are ionizing radiation, and are thus biologically hazardous.

Everyday Applications

1. Gamma rays are given off by stars, and by some radioactive substances.

2. They are extremely high frequency waves, and carry a large amount of energy.

They pass through most materials, and are quite difficult to stop - you need lead or concrete in order to block them out.

Health Impacts

Positive: Radiation treatments following breast cancer surgery such as a lumpectomy can help stop further cancer cell growth, according to the American Cancer Society.

Negative: Gamma rays can alter or harm healthy cells in the body. As a result, tumors or cancerous cells may continue to grow. Gamma rays are also the energy which is involved in some of the most tragic accidents.
