Abstract
⺠Model for detection of two annihilation quanta is proposed. ⺠Two NaI(Tl) detectors with almost 4Ï geometry was used for coincidence γ detection. ⺠Absolute activity measurement of 94Nb source with coincidence emission of two γ in cascade is performed. ⺠Activity measurements of 22Na and of 26Al sources with positron-γ coincidence emission are performed.
