OBJECTIVE: With the aim of reducing and preventing environmental damages, handling and disposing practices of chemical effluents from radiology departments were investigated and a service management model was created in order to obtain financial resources for the department. MATERIALS AND METHODS: The proposed model, based on the evaluation of chemical effluents from automatic processors of radiographic films, showed that fixer reprocessing can be an adequate choice to solve environmental and financial problems in these departments. This model also emphasizes that compliance with management guidelines should be observed, i.e. other effluents (developer and water) must be chemically treated before disposal in the natural environment. The economical analysis has confirmed that the income originated from commercializing the silver (of which concentration ranges from 3.5 to 10.2 g/l), recovered from the used fixer, in addition to the income from the reuse of the fixer (after its recovery), is in the worst scenario (when the silver concentration is 3.5 g/l) enough to cover all the expenses with the implementation of the project. CONCLUSION: The proposed model can be a good choice for solution of environmental and financial problems. Moreover, it is ecologically correct, a potential source of financial resources to radiology departments, and can be applied to other institutions due to the similarity of problems and resources.
