Several of the positron emitters are useful in PET studies.
T
hat usefulness is somewhat offset by the cost of producing
the radionuclides and the added complexity of radiation
protection. For all of the positron emitters the energy of the
Beta+ must be considered. Refer to the table of Beta Dose
Rates for estimates of beta+ radiation exposure. Also,
consider the annihilation photons when the positron comes
into contact with a beta-, annihilating their masses and
producing two 511 KeV photons. These photons present an
external radiation hazard. For the patient undergoing a PET
scan the combination of the positron energy and the photon
energy must be considered.
