Programs
  Programs of radiation protection are implemented with the aim of assessment of doses to Lithuanian population, evaluation of possible impact of radiation, identification of measures needed for optimized radiation protection. The Radiation Protection Centre implements programs of different size, complexity and duration.
 
   Recently programs with the aim of assessment of doses to members of public due to foodstuff, drinking water, natural radioactivity, internal and external doses to radiation workers, doses to patients are performed.
 
   Radiological monitoring of foodstuff and drinking water is performed according to the Commission Recommendation 2000/473/EURATOM of 8 June 2000 on the application of Article 36 of the Euratom Treaty concerning the monitoring of the levels of radioactivity in the environment for the purpose of assessing the exposure of the population as a whole. The Radiation Protection Centre performs radiological monitoring of mixed diet, milk and water. Monitoring of mixed diet is done with the aim of determination of concentrations of artificial radionuclides such as Cs137 and Sr90. Concentrations of natural radionuclides are also recorded. Samples of meat, fish, vegetables and cereals are analyzed. Cooked food is also sampled for measurements. Concentrations of natural and artificial alpha and beta radionuclides and tritium are investigated in drinking water. Water both from individual wells and central water supply systems is analyzed.
 
   The data of monitoring are presented to all the interested institutions and society. They are also supplied to the data basis of EC.
 
 
Programme on Assessment of Human Exposure to Indoor Radon (2017-2023)

    Measurements of indoor radon concentrations in dwellings, public places, education and work places are foreseen in the Programme. Data on additional radon measurements will be included into the Lithuanian and European indoor radon mapping. Radon–related lung cancer risk among Lithuanian population will be assessed in accordance with latest epidemiological models. Different individual groups will be involved (general public, students, workers). Cooperation on the application of radon prevention and mitigation measures are being established with the specialists of the construction sector. In addition, cooperation with representatives of municipal administrations, public health and other specialists to be continued.

 

Programme on Searching of Orphan Source in Living Environment ( 2017-2023)

 

   In recent years, territory contaminated with 226Ra of concentration above the exemption level was identified while  implementing previous approved programs for the search of orphan sources and radioactive materials. After the discovery of the contaminated site, protective measures were taken to prevent further exposure of the public and the area was remediated.

   In 2016, residents informed about two sites that caused those suspicions about the possible use of radioactive materials in those territories in the past. A search campaign is planned in these territories while implementing the Programme. Radiation protection Centre (hereinafter – RSC) also appealed to all municipal administrations within the country with ask to indicate the areas where search of orphan sources and radioactive materials will be expedient according to available data or occurred suspicion.  The municipalities of Vilnius, Alytus and Kazlų Rūda informed that they have past Soviet Army military sites with unknown activities in the past. The municipalities intend to perform searching for orphan source and radioactive materials in those territories. Furthermore, search of orphan sources during mass public events using mobile ionizing radiation detection system MDS is also foreseen.

 

Monitoring of wood and other biofuel contamination with 137Cs radionuclide in 2017-2023

 

137Cs radionuclide was dispersed into the environment after an accident at Chernobyl NPP and till now it is source of exposure for population. When wood contaminated with 137Cs, burned at stokehold, 137Cs concentrates in ashes. The ashes are commonly used to fertilize soil and forests. 137Cs radionuclide from the soil absorbs in plants, gets to milk, meat and other agricultural products through the food chain enters human body and causes internal exposure. Ashes with higher 137Cs activity concentration are used in civil engineering.

Implementing the program, samples of wood will be systematically selected from Lithuanian forests and radiologically investigated.

Wood fuel is imported to Lithuania from Belarus, Ukraine and some regions from Russian Federation. During radiation protection inspections on state border samples of imported wood fuel will be taken and contamination with 137Cs will be radiologically investigated. Samples of wood ashes from stokeholds will be investigated as well. The information obtained from research will be used for evaluation of contamination of Lithuanian forests. This information will be presented to state institutions, society and will be published at Radiation Protection Centre internet site.
