All matter is in random motion and emits energy. What is the difference between regular motion and radiation?
RADIATION components of an atom are discharged at: less than the speed of light, but lots faster than normal molecular speed (particles) at the speed of light (waves)
C 12 6 Protons (+) need neutrons to hold them together Ra Zn 226 88 65 30 Lighter elements: # of protons = # of neutrons Heavier elements need more neutrons to offset repulsion of + protons U 238 92 A nucleus will rearrange its n:p ratio until it is stable - particles are emitted (radioactivity) Pu 244 94
Radium It glows in the dark
RADIATION particles have mass: protons, neutrons, electrons waves have zero mass: gamma rays
RADIATION does its damage through IONIZATION
Electrons in search of a nucleus
Gamma rays don’t search for anything, they just destroy as they zoom along
