A radiation detector at a nuclear facility records individual decay events. It records beta-minus decay, beta-plus decay and gamma emission from excited nuclei.
State where in the atom a beta-minus particle is made.
For a beta-minus event recorded by the detector, give the name of the particle inside the nucleus that changes identity.
For a beta-plus event, give the charge number, relative to a proton, of the emitted particle.
The detector identifies the particle emitted during beta-plus decay. Give the relative mass of this particle in comparison with an electron.
The detector records gamma radiation from an excited nucleus. State how the energy of the nucleus changes when the gamma radiation is emitted.
