title: [The psychodynamics of work with iodine-131 in nuclear medicine].
abstract: This paper seeks to demonstrate to what extent alternative forms adopted in the working process of professionals with iodine-131 in nuclear medicine can assist in managing risks of ionizing radiation. The design is based on the main theoretical concepts of the psychodynamics of work in relation to workers' health. In the case study, data were gathered from 15 workers of a public health institution in the city of Rio de Janeiro by means of semi-structured individual interviews and non-systematic direct observation. Bardin's content analysis method was used for the data analysis. When comparing the results obtained with standard prescribed models, it was found that the respondents had changed their approach. They developed individual defense mechanisms, such as denial of risk, and collective defensive strategies, leading them to tackle the greatest danger as a form of defense. The defensive role of ideologies of the profession are manifest. On the contrary, the acquired knowledge derived from prudence proved effective in minimizing the risks of radiation exposure. The authors discuss the limitations of security management that does not consider the workers' subjectivity and inherent knowledge.
