d at various levels Vd of discrimination within definite interval inside which absolute value of slope of dependence of Nd or nd on Vd takes minimum value are measured. At least one measurement is taken in definite subinterval with allowance for discrimination level Udm at which absolute value of slope of dependence of Nd or nd on Vd takes minimum value. Measurement results in this subinterval are approximated by means of inverse exponential function f(Vd) depending on the square of argument. Then value Q of average charge is found. Process provides for precision measurement of Q in fission chambers depending on number of measurements in subinterval with reliability of 95%. EFFECT: increased precision and reliability of process. 1 cl, 6 dwg, 5 tbl"/>
