1 Comparative analysis of aberration yields induced by radiation with different LET (Linear Energy Transfer) University of Warsaw Jakub Pietrzak UW University of Gdańsk Magdalena Rojek Monika Szymanska AGH University of Science and Technology Anna Kaminska Dominika Kedzierska Ewa Lagudza

2 2 THE DREAM TEAM

3 3 Laboratory of Radiation Biology Marta Deperas- Kaminska (supervisor) Ekaterina Zaytseva

4 4 The practice purposes: Theoretical introduction to cytogenetic methods used in biodosimetry Instructions of safety rules of work with human blood samples. To learn how to irradiate human lymphocytes and culture them under experimental conditions. Be able to carry out a simple experiment and analysis with irradiated cells

5 5 SCHEME OF THE EXPERIMENT Incubation for the standard metaphase analysis colcemid 47h Fixation Staining with Giemsa 50h Standard light microscope Radiation

6 6 Our experiment Picture 2 Lymphocyte 1. Irradiation of blood samples with different LET radiation 2. Lymphocytes culture (48 hours) Picture 1 Blood

7 7 3. Lymphocytes fixation 4. Giemza staining 5. Analysis of chromosomes aberrations Picture 3 Chromosomes Picture 4 Chromosomes 2

8 8 Dic Centric ring Acentric ring deletion ace Unstable aberrations - dicentrics, acentric fragments and centric and acentric rings in Giemsa stained metaphase

9 9 The increase of aberration yields with increase of radiation LET in human peripheral blood lymphocytes is observed. RESULTS:
