TRANSISTORIZED_GEIGER_COUNTER

Published:2009/7/19 21:14:00 Author:Jessie | From:SeekIC

Rate-meter circuit converts output of halogen-type counter directly into meter indication corresponding to radiation intensity. Counter triggers two-transistor switch to place low-impedance load across conventional dual-output diode pump. Two halves of pump current are summed in metering circuit.-F. S. Goulding, Transistorized Geiger Counter Fits in Probe, Electronics, 32:3, p 64-66.
