MULTICHANNEL REMOTE DOSIMETER Russian patent published in 2018 - IPC G01T1/18 

FIELD: nuclear physics and equipment.

SUBSTANCE: invention relates to radiation safety and can be applied for distributed monitoring of ionizing radiation levels. Multichannel remote dosimeter contains sensors based on Geiger-Muller counters, a power supply module, a microcontroller, each sensor is equipped with a matching transformer, the primary winding of which is serially connected to a Geiger-Muller counter and connected to a high-voltage converter, the secondary winding leads are connected to the comparator inputs via a two-wire communication line, the output of which is connected to the input of the T-flip-flop, the output of which is connected to one of the inputs of the microcontroller, with the transformation ratio chosen so as to match the high internal resistance of the Geiger-Muller counter to the low characteristic impedance of the communication line.

EFFECT: increased radiation resistance of a multichannel remote dosimeter.
