Chapter 11 notesCurrent LectureChapter 11-radiation can disrupt chemical processes in cells and can damage DNA, which may cause mutations-nuclear equations represent nuclear processes; the equations are balanced when the sum of nucleon numbers on each side is the same and the sum of atomic numbers on each side is the same-four types of radioactive decay: alpha decay, beta decay, gamma decay and positron; the fifth type is electron capture which absorbs one of the atom’s electrons-transmutation is the conversion of one element into another, it can’t be carried out bychemical means but can be by nuclear processes-the different types of radiation have different abilities: alpha particles-slow and penetrating; beta particles-faster and more penetrating; gamma rays-travel at the speed of light and have great penetrating power-the goals of the Manhattan Project-to achieve sustained nuclear fission and determine the critical mass; to enrich the amount of fissionable material required; synthesize plutonium; to construct a nuclear fission bomb before the Germans -nuclear power plants use the same nuclear chain reaction as in atomic bombs, but it’smuch slower and can be controlled These notes represent a detailed interpretation of the professor’s lecture.
