A method for determining ionizing radiation including applying a constant voltage across an organic semiconducting material sensor prior to and after exposure of the sensor to the ionizing radiation; measuring and converting the current passing through the sensor proportional to the conductivity or resistivity of the sensor which in turn is proportional to the ionizing radiation in the sensor, into a proportional analog voltage value; and comparing the value obtained prior to and after exposure of the sensor to the ionizing radiation and computing the ionizing radiation based on the change in the value. An electronic device for determining ionizing radiation including an organic semiconductor resistor, a constant voltage source, and to a current to voltage converter, an analog to digital converter, and a microprocessor.
