The diploma thesis deals with the identification of risks which threaten students in the fields of Radiology Assistant, General Nurse and Paramedic. The aim of the thesis is to map the knowledge of risks during providing health care in students of selected fields at the Faculty of Health and Social Studies at the University of South Bohemia. Four hypotheses were set in the thesis. Hypothesis no. 1 saying that there are statistically significant differences in risk knowledge between students of the first and last year of individual fields of health care. Hypothesis no. 2 that there are statistically significant differences in stress perception as a risk-enhancing factor between paramedics and general nurses. Hypothesis no. 3 states that there is a statistically significant difference in the knowledge of the risk of ionizing radiation between radiological assistants and general nurses and hypothesis no. 4 that paramedics will call their future occupation more risky than general nurses. To achieve the objectives and verify the hypotheses, a questionnaire was prepared, a questionnaire survey was conducted and everything was evaluated using graphic and statistical methods. The questionnaire contained 23 questions and the research sample consisted of 105 respondents from the studied fields. The results show that hypothesis no. 1 was confirmed in the fields of Radiology Assistant and Paramedic and rejected by the General Nurse. Hypothesis no. 2 was also confirmed. Hypothesis no. 3 was rejected and hypothesis no. 4 was also rejected. The contribution of the thesis is a complex picture of the knowledge of risks during providing health care in the studied fields. The results can serve the faculty to further more effective teaching.
