This work aimed to develop a teaching proposal on the content of radioactivity, focusing on its applications in medicine, particularly the use of Iodine-131 in radioiodine therapy, using a CTS approach. The research was developed with 16 students from the 3rd year of high school who were between 16 and 19 years old, from a school located in the city of Ribeirão-PE. For the methodology, a didactic sequence was applied, involving four moments, where debates, case studies and questionnaires took place. The questions were thought and organized in a way that brought answers about the level of previous knowledge of the students, where this knowledge was acquired and the evolution of the student's knowledge after a case study. Through this classroom research, the result showed that a good part of the students had an unsatisfactory knowledge about scientific concepts and a moderate knowledge about the applications of radioactivity, the latter acquired outside the school environment, through the internet, movies and series. With the application of the didactic sequence, the students had the first deeper contact with the content, getting to know the different concepts, applications and relationships with science, technology and society, showing themselves to be more motivated and interested in the theme.
