Working hours

Access to the laboratory is granted to persons permitted to work under exposure to ionising radiation and authorised to access the laboratory. The doors to the laboratory have a magnetic lock. Authorised persons can obtain a magnetic card from the Administration.


Ground floor in building A, entrance through room no. 16.

Abbreviated description of conducted work

Scientific staff and PhD students use the laboratory to carry out basic and applied research in the fields of biological and chemical sciences.

In the class II laboratory, it is permitted to work with higher activities than in the class III labs. The maximum allowed single isotope activity in the used compounds may reach:

  • H-3 up to 1TBq  (27,7 Ci)
  • C-14 up to 100 GBq (2,77 Ci)
  • S-35 up to 100 GBq (2,77 Ci)
  • P-32 up to 100 GBq (2,77 Ci)
  • I-125 up to 100 GBq (2,77 Ci)

Laboratory equipment

  • dosimetric instruments,
  • fixed and movable organic glass shielding and radioactive waste containers to guarantee full shielding from the radiation used,
  • a scintillation counter,
  • eight workstations for working with isotopically-labelled compounds, including two workstations under fume hoods,
  • a double station for electrophoresis with dedicated equipment,
  • four hybridisation ovens with thermostats,
  • refrigerators and freezers,
  • a precise scale (210 g – 0,001 g),
  • small laboratory equipment: heating baths, shakers, table-top centrifuges, stands, etc.
