MEASUREMENT SYSTEM FOR AMOUNT OF RADIATION AND MEASURING METHOD USING THE SAME

摘要

PURPOSE: A system for measuring exposure and a method for measuring exposure using the same are provided to enhance the accuracy on a measurement by correcting energy dependency in a low energy area. CONSTITUTION: A method for measuring exposure is as follows. Phantom(50) connected to a high-sensitivity MOSFET dosimeter(100) is arranged at a radiation emitting field. The radiation exposing condition illuminated to the phantom is input. A calibration factor and a dose correction factor are applied to the high-sensitivity MOSFET dosimeter for the exact dose measuring of the exposed value of the phantom. The inner dose of the phantom is read in a real time. The long-term dose and the effective dose of the phantom are measured. The long-term dose and the effective dose are analyzed to determine the suitability of the exposure.
