OBJECTIVE: To evaluate the biosafety aspects and the working conditions of radiology department professionals and to make recommendations with respect to necessary modifications to be implemented in these departments in order to comply with national regulations. MATERIALS AND METHODS: Interviews with the professionals were carried out as well as observation of their activities in the working premises including processing of radiographic films inside the dark rooms, average time inside the dark rooms, preparation of chemical solutions for automatic processors and the type of help given to patients during radiographic examinations. The efficiency of the exhausting systems in the dark rooms was also measured. The ergonomic adequacy of the accessories inside the dark rooms was analyzed. With respect to electrical safety, the location and number of fire extinguishers as well as the grounding of the electrical equipment was evaluated to check if they were in accordance with the Brazilian legislation. RESULTS: The exhaustion systems were insufficient, professionals did not wear protective clothes/devices when preparing the chemical solutions, the ergonomic aspects were not in accordance with national recommendations, and the workers presented related stress. CONCLUSION: Based on these results, risk maps were drawn for each sector of the radiology department to be used in the implementation of improvements in each sector.

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.
