-Have frequencies of more than 10 exahertz (>10^19 HZ). 
-Produces energies of a few hundred keV. ]]> 2018-04-30 17:05:25 UTC https://padlet.com/54871/owow815xu8sc/wish/256613196 54871 https://padlet.com/54871/owow815xu8sc/wish/256615650 Gamma rays are used in medicine to treat internal organs. Gamma rays kill cancer cells, sterilize medical equipment and are used in radioactive tracers. ]]> 2018-04-30 17:10:28 UTC https://padlet.com/54871/owow815xu8sc/wish/256615650 54871 https://padlet.com/54871/owow815xu8sc/wish/256616958 https://courses.lumenlearning.com

This is because they can penetrate the skin and damage the cells inside. ]]> 2018-04-30 17:16:13 UTC https://padlet.com/54871/owow815xu8sc/wish/256618503 54871 https://padlet.com/54871/owow815xu8sc/wish/256618905 -Gamma rays are considered as ionizing radiation whose scattering by electrons and nuclei leads to the creation of a radiation field. This field contains negative electrons and positive ions. 
-They interact in photoelectric and photonuclear forms.
