Fixer radiography
WebPhotographic fixer is a mix of chemicals used in the final step in the photographic processing of film or paper. The fixer stabilises the image, removing the unexposed silver halide remaining on the photographic film or photographic paper, leaving behind the reduced metallic silver that forms the image. WebThe majority of problems in radiography can be traced to improper film pro-cessing procedures. Quality control of processing is the most effective way to avoid these problems, and the most effective way to achieve high-quality radiographic images consistently . Effective quality control for automatic processing begins at each solution change: 1.

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: http://01f2151.netsolhost.com/blackboard/GaXray/Reading/Quality_Assurance_in_Dental_Radiography.pdf
