METHOD AND APPARATUS FOR DETERMINING ENERGY CALIBRATION OF RADIATION DETECTOR, DEVICE, AND MEDIUM

Abstract: provided are a method and an apparatus for determining an energy calibration of a radiation detector, a device, and a medium. the method includes: acquiring (s) a background energy spectrum of a plurality of known nuclides, where the background energy spectrum is obtained by the radiation detector detecting the plurality of known nuclides; performing (s) differential processing on the background energy spectrum to obtain a channel address-difference diagram, where the channel address-difference diagram includes a plurality of valid peak information determined from a plurality of full-energy peak information; determining (s) a target coefficient according to the channel address-difference diagram, where the target coefficient characterizes a calibration coefficient in initial energy channel address function; and determining (s) a target energy channel address function according to the channel address-difference diagram and the initial energy channel address function, where the target energy channel address function characterizes the energy calibration of the radiation detector. the apparatus for determining an energy calibration of a radiation detector includes an acquisition module (), a differencing module (), a first determination module (), and a second determination module ().
