one radioactive decay per second
one is defined as 3.7 x 10^10 decays per second
the registration of a single decay by a detector
atoms of different elements with identical numbers of nucleons
atoms of different elements that contain identical numbers of neutrons but different protons
interaction when a small charged particle is deflected by the nuclei as it passes through matter
measurement of gamma or x-ray radiation exposure in air
light-sensitive material usually a type of semiconductor on the end of a photomultiplier tube
restricts photon entry to the crystal so each point in the image corresponds to a point in the source
when it is removed from a PET detector it increases sensitivity but decreases the resolution
measure of readings of the dose calibrator in comparison with well-accepted standards
tests the calibrator over a range of doses
half-life that is the time it takes for half of the nuclide atoms to become stable
half-life that reflects the half-time for excretion of the material from the organ or whole body
