DEVICE FOR MEASURING RADIOACTIVE RADIATION INTENSITY Russian patent published in 1996 - IPC

FIELD: measuring circuits. SUBSTANCE: device has detector, detector pulse counter, generator, generator pulse counter, controlled counter, controlled counter scaling factor setting unit, reset pulse shaping unit. In addition, it is provided with two capacitors, 2NOR gate, control counter. Novelty is new design of controlled counter made as binary counter connected in series with multiplexor, building of reset pulse unit around RS flip-flop and new design of scaling factor setting unit made as binary counter, as well as new connections between old and newly introduced units. EFFECT: enlarged functional capabilities due to introduction of automatic control of channel-timer scale following logarithmic law depending on value being measured. 5 dwg
