coincidence counting

[kō·in′sidəns]
Etymology: L, coincidere, to occur together
the detection of two photons that arrive at separate counters simultaneously as the result of annihilation of a positron (created during a radioactive decay) and an electron. Coincidence counting greatly reduces the significance of any background radiation in radiography.
