METHOD FOR THE Y-COMPENSATION OF AN IONIZATION CHAMBER HAVING AT LEAST ONE MEASURING ELECTRODE AND AT LEAST TWO POLARIZATION ELECTRODES, ONE OF WHICH SERVES AS COMPENSATION ELECTRODE, WHILE UTILIZING A CURRENT MEASURING DEVICE COUPLED TO THE MEASURING ELECTRODE AND TWO VOLTAGE SOURCES, WHICH ON THE ONE HAND ARE CONNECTED TO THE POLARIZATION ELECTRODES AND ON THE OTHER HAND TO THE CURRENT MEASURING DEVICE, WHEREIN THE VOLTAGE SOURCE CONNECTED WITH THE COMPENSATION ELECTRODE DELIVERS A POLARIZATION POTENTIAL DESIGNATED AS COMPENSATION POTENTIAL; COMPRISING THE STEPS OF: PERIODICALLY REVERSING DURING A TIME INTERVAL ($T) THE POLARITY OF THE COMPENSATION POTENTIAL (U2) AT AN IONIZATION CHAMBER INTENTIONALLY MADE OVERCOMPENSATED IN THE CONVENTIONAL SENSE, SO THAT A FRACTION OF THE COMPENSATION CURRENT OF THE IONIZATION CHAMBER CAN BE RETURNED TO THE MEASURING ELECTRODE, AND REGULATING THE Y-COMPENSATION BY ADJUSTING THE RATIO ($T/T) OF THE TIME INTERVAL ($T) OF EACH REVERSAL TO THE PERIOD (T) OF SUCCESSIVE REVERSALS.
