Document Summary

An inert gas tube that conducts electricity when a paricle/photon of radiaion temporarily makes the gas conducive by ionizing it. Half-lives vary for dif isotopes of the same atom. Nuclear kineics dn/dt = counts/s (or min, hr, ) = slope of n vs t. Mass of nuclide is not equal to the sum of the masses of individual nucleons in the nuclide. Mass defect is equated to the energy required to hold the nuclear paricles together. Produced when mass m is converted into energy/consumed when energy is converted to mass. Nuclear binding energy= energy required to separate nucleus of atom into protons and neutrons. The greater the binding energy/nucleon, the more stable the nucleus. Be/nucleon also a guide to the type of nuclear reacions nuclei will undergo.
