[X-ray dosimetry using a charge injection type condenser].
An X-ray dosimeter has been investigated with the use of a charge injection type condenser. The detector is small size and is housed in an epoxy resin approximately 4.5 X 2.5 X 1.5 mm. The X-ray dose can be determined by decreasing the amount of electron injected into floating gate through X-ray irradiation. The X-ray irradiation dose can be measured by decreasing of the capacitance. This dosimeter shows good linearity but the X-ray energy response for low energy region is higher than high energy region.
