ESR MEASURING METHOD OF RADIATION DOSE

摘要

PURPOSE:To obtain the ESR measuring method which a chieves a simple and highly accurate measurement of a dose of radiations such as gamma rays X rays using an alanine element. CONSTITUTION:An average value which is obtained by adding an ESR signal intensity of an alanine element which is inserted into a cavity resonator of an ESR device and that which is obtained by measuring the ESR signal intensity again by rotating a material by 90 degrees with the direction of insertions as an axis and then dividing it two portion is a relative radical concentration which the alanine element originally has. A target dose of gamma rays is obtained by fitting this value to dose response curve with the alanine element relative radical concentration as Y axis.
