Radioactive Decay, Half-Life, Nuclear Reactions
All radioactive decays are first order in # of radioactive nuclei
Half-life: t at which half original nuclei have decayed; t1/2 = 0.693/k
Use half-lives and k to date organic archaeological samples and rocks
Nuclear fusion generates the energy of the stars including the sun
Nuclear reactions are used to generate power in nuclear power plants; and in nuclear weapons as used in WWII
Nuclear power plants major concern is storage or disposal of nuclear wastes
