Nuclear Particles • Alpha particle • Beta particle • Gamma particle a 4 2He β g
Alpha Decay • Alpha particles are a helium nucleus with a +2 charge…
Beta Decay • Beta particles are fast moving electrons with no mass and -1 charge…
Gamma Decay • Gamma radiation is like light and energy from an explosion…it occurs with alpha or beta decay as a secondary product.
Nuclear ReactionsNuclear Fusion • Nuclear Fusion… Combining of 2 smaller nuclei to make one larger nucleus. • We cannot conduct nuclear fusion to produce energy because it requires too much energy input and too much hear.
Nuclear Fission • Nuclear Fission is the reaction used to power submarines, aircraft carriers, and nuclear power plants. • Fission is the splitting of atoms into 2 smaller nuclei.
Detecting Radiation • Gieger counters count electron strikes in a gas tube. • Scintilation counters count electron strikes to a phosphorescent screen. • Film ID badges are worn by employees and analyzed at night or at the end of the week to see radiation strikes.
