WebUsed X-ray fixer is a hazardous waste (RCRA waste code D011) because of its high silver content (the regulatory level is 5 mg/l silver, used fixer typically contains 3,000 to 8,000 mg/l of silver). As such, it cannot be sewered or disposed of as common solid waste. There are three common ways of dealing with used fixer:
WebT or F: Digital radiography systems require 50-80% more exposure than conventional radiographic units. True T or F: Digital images are electronic signals captured by a sensor. True T or F: A special kind of film is required to duplicate a radiograph. True T or F: Duplicating radiographs does not require the use of x-radiation. before processing
