To provide a sorter of bromine-based flame retardant-containing plastic using X-ray detection, for invalidating an influence of decline of detection sensitivity in long-hour continuous operation.
This sorter of bromine-based flame retardant-containing plastic includes: an X-ray source for generating an X-ray; a sample holding device for holding a plastic sample; an X-ray detector for detecting an X-ray transmitted through the plastic sample; a bromine inclusion including bromine having a regulated concentration; a data processing device for performing data analysis of intensity of transmission X-rays detected from the plastic sample and the bromine inclusion, and discriminating the quantity of the bromine-based flame retardant contained in the plastic sample; and a sorting mechanism for sorting the plastic sample having a bromine concentration higher than the regulated concentration of the bromine inclusion based on a signal from the data processing device.
