OBJECTIVE: The main objective of the present study was to evaluate radiodiagnosis services in two public hospitals with x-ray equipment in the city of Rio Branco, Acre, Brazil. MATERIALS AND METHODS: Interviews, measurements and direct observation were performed, following the Brazilian legislation in force, especially the Order (Portaria) SVS/MS 453 of 1998 of the Ministry of Health establishing the basic guidelines for radiation exposure protection in medical and odontological x-ray facilities. RESULTS: The data indicated a high rate of non-compliance with the legislation in both radiological services, especially concerning poor equipment operation, and non-compliance with some safety protocols. CONCLUSION: Basically, technical and operational infractions have occurred as a result of a broad unfamiliarity with the legislation, the absence of a preventive equipment maintenance program, besides low investment in training and/or courses for professional updating. Therefore, a considerable number of simple and complex changes are demanded to improve the quality of the investigated radiodiagnosis services.
