METHOD FOR DETERMINING FLUENCY RATE OF NEUTRONS Russian patent published in 1994 - IPC

FIELD: neutron radiation metering technique. SUBSTANCE: method involves avalanche mode of operation of bipolar transistor and measurement of breakdown voltages in common-base connection with emitter held open and in common-emitter connection with base held open before radiation as well as in common-emitter connection with base held open upon radiation, after which fluency rate F of neutrons is found from equation given in description of invention. EFFECT: improved sensitivity and facilitated procedure. 2 dwg
