A radiation dosimeter is described comprising: at least a first capacitive ionization chamber adapted to gradually discharge in the presence of incident radiation; a voltage source; a load resistor coupled to the voltage source; a first switch means coupled to the load resistor and the voltage source to form a first in-series circuit comprising the voltage source, the load resistor and the first switch means; a second switch means coupled to the load resistor and the voltage source to form a second in-series circuit comprising the voltage source, the load resistor, the second switch means and at least first capacitive ionization chamber; peak voltage sensing means coupled across the load resistor for providing a peak voltage signal; and calculating means responsive to peak voltage measurements taken across the load resistor as the first and second switch means are sequentially actuated for calculating the amount of radiation incident on the dosimeter from the peak voltage measurements.
