Effects of Electromagnetic Waves Flashcards
form of energy that acts by removing electrons from atoms and molecules of materials that include air, water, and living tissue
Ionizing
form of low energy radiation that does not have enough energy to remove an electron from an atom or molecule
non ionizing
Ionizing in electromagnetic spectrum
ultraviolet, x rays, gamma rays
non ionizing in electromagnetic spectrum
radiowaves, microwaves, infrared, visible light
harmful effects of ultraviolet
sunburn
skin cancer
cataracts
harmful effects of visible light
over exposure can damage both eyes and skin
harmful effects of infrared
damaged eyes
blindness
greenhouse effect
harmful effects of microwave
cataracts
skin
harmful effects of radio frequency
can warm up exposed parts of the body
harmful effects of lasers
can burn and severe damage to our body
damage the eye
LASERS
Light Amplification by Stimulated Emission of Radiation
harmful effects of alpha radiation
can damage sensitive living tissue
harmful effects of beta radiation
penetrate skin
harmful effects of gamma radiation
destroy living cells
produce gene mutation
cause cancer
what material can be stopped by gamma waves
thick or dense enough layer of material with high atomic number materials
harmful effects of x-ray
radiation burns
damage healthy living cells of the body
cause mutations in our DNA
may lead to cancer
classified as a carcinogen
harmful effects of neutron radiation
damage soft tissues like the cornea of the eye
cause cells to change in their functionality or stop replicating
