EM Waves: Gamma
By: Katie Kelly
What is a gamma ray?
It is a penetrating electromagnetic radiation of a kind arising from the radioactive decay of an atomic nucleus.
Uses:
2. GRS (Gamma-Ray Spectrometer)- measure gamma-rays given off by an atom's nucleus and helps determine the elements on other planets
3. Stars- give off gamma-rays, and Supernovae emit gamma-rays also
4. Nuclear bombs- produce gamma-rays

New Technology
HYBRID POLYMER GAMMA-RAY SHIELDING MATERIAL
Materials: This invention is made of a polymer compound (a chemical compound that is made of small molecules that are arranged in a simple repeating structure to form a larger molecule) that is 13 centimeters thick.
Impact: This technology has not been released yet, but it will impact our lives greatly by shielding harmful gamma-rays that we would have otherwise not have been protected from. For example, people who are in the areas where gamma radiation is used or create will be protected by this material.
Date Discovered: (no specified date) first tested on September 8, 2008
Person(s) Involved: Miss Sukran CAN (inventor of material)
