Resumo
Radioactivity was discovered in the 19th century by Becquerel, Marie and Pierre Curie, was seen with enthusiasm by everyone and radioactive materials started to be used for the most diverse purposes. One of the areas of great application of radioisotopes is medicine, both in diagnosis and in the treatment of cancer. Cesium 137, is one of the radioisotopes that was used in radiotherapy equipment and later would become the material cause of the radiological accident that occurred in Goiânia in 1987, when collectors of recycled materials found an abandoned radiotherapy device, and saw the opportunity to earn money by selling the lead contained in the equipment. In this way, this article sought to (re)do a reading of this accident from the Freirean perspective, seeking to understand the social relations that emerged in the context of the actions imbricated in the history of the accident and its consequences. We understand that this accident could have been avoided if those involved had basic knowledge about symbols related to the scientific context and specifically to radioactivity, which highlights the importance of attending a school and the development of an education capable of providing students with the appropriate of scientific knowledge through scientific literacy.
