MEASUREMENT METHOD, APPARATUS, AND RAY MEASUREMENT DEVICE

This application discloses a measurement method and apparatus, and a radiation measuring device, and relates to the field of battery technologies. The method includes: determining a measured mass parameter of a workpiece being measured based on radiation intensity of rays that have passed through the workpiece being measured; and correcting the measured mass parameter by using a displacement curve function of the workpiece being measured in a measurement environment, to obtain the corrected mass parameter of the workpiece being measured, where the displacement curve function is used to characterize influence of environmental factors on radiation in the measurement environment.
