Biological dosimetry relies on the use of physiological, chemical or biological markers of exposure of human tissue to ionizing radiation (assays). These assays enable the reconstruction of doses to individuals or populations which, in turn, are used to provide an assessment of the damage from occupational or accidental exposure to ionising radiation. Biological dosimetry, which is most useful in the management of irradiated persons, can also be used to optimize cancer therapy regimes.

The IAEA has provided Lithuania with support in the establishment of a new Biological Dosimetry Laboratory within Lithuania’s Radiation Protection Centre (RPC). The new, dedicated premises are equipped with stateof- the art instrumentation to perform assays using traditional cytogenetic techniques, as well as the more advanced ‘fluorescence in situ hybridization’ (FISH) method. Two junior laboratory staff have received comprehensive, hands-on training in top institutions in the region, gaining knowledge and experience in operating the new equipment according to best international practices.

The project has contributed significantly to building national capabilities for cytogenetic analysis of ionizing radiation exposure and biological dose assessment. On 5 November 2013, the new Biological Dosimetry Laboratory was inaugurated in the presence of the Health Policy Advisor to the Prime Minister of Lithuania. Since then, the laboratory has become fully operational. Ongoing collaboration with national oncology centres in support of optimized cancer therapy will help to ensure its sustainability. The results of the project mark an important step towards further enhancing Lithuania’s radiation safety infrastructure in the field of emergency preparedness and response.
