[en] The article presents the measurement results of the volumetric activity (VA) of artificial radionuclides 90Sr and 137Cs in the coastal waters of the Baltic Sea near the Curonian Peninsula in 2005-2009. The annual average values for this period of time were 12 Bq/m3 (90Sr) and 40 Bq/m3 (137Cs). Considerable variations in the VA of the radionuclide in individual measurements compared to the average results were observed. The extreme values were 6 and 16 Bq/m3 for 90Sr and for 137Cs-27 and 75 Bq/m3. It is proposed to allow such variations under the influence of a variety of external factors such as hydro meteorological situations, inflowing rivers and bays, storm activity and etc. Besides, a possibility of penetration of radionuclides into the sea waters from the additional radioactive sources is not excluded.

[en] The state system of radiation protection is still being created after Lithuania regained its independancy and in connection with recommendations laid in the ICRP-60 publication and requirements of legislation of European Community. A new regulation institutions was established and a number of laws and regulations related to radiation protection was prepared. The Radiation Protection Centre of Ministry of Health is the regulatory authority responsible for radiation protection of public and of workers using sources of ionizing radiation in Lithuania. A new Radiation Protection Law, Nuclear Energy Law, Radioactive Waste Management Law and different regulations was approved. Preparation of legislation, creation of state system of radiation protection and its upgrading allow to presume that the necessary level of radiation protection is to be achieved. (au)

[en] The purpose of this report is to analyse the physical and radiobiological background of the HDR Cf-252 Neutron brachytherapy boost in the combined radiation therapy for locally advanced prostatic cancer. The treatment schedule:two fractions of the Cf-252 brachytherapy(5Gy-eq at the dose point 2 cm from source movement trajectory) with interval 24 hours; 5-8 fractions of the photon beam external radiation therapy(5 fractions per week, 2 Gy per fraction) to the prostate, two fractions of the Cf-252 brachytherapy and after that external beam radiation therapy is continued till total dose 40-45 Gy. Six patients completed the proposed combined radiation therapy. The results of this trial will be discussed

[en] The physical and chemical characteristics of radon gas make it a good tracer for use in the application of atmospheric transport models. Radon exhalation rate from soil is one of the most important factors for evaluation of the environmental radon level. For this purpose to find out the volumetric activity of radon in ground-level air the measuring has been made using radon monitor SARAD RTM 2200. Radon volumetric activity and radon exhalation rate in ground-level air and at different depths of soil depending on soil temperature and atmospheric parameters in different seasons of the year was calculated and evaluated in two areas of Vilnius city. It has been established that the volumetric activity of radon and radon exhalation intensity is vertically distributed and the corresponding increase in deeper soil layers, and depends on the specific activity of radium, soil temperature and moisture content, temperature difference between soil and atmospheric temperatures.

[en] An overview of Lithuania nuclear sector is presented. Status of art and main problems are presented. Lithuania operates the biggest in the world RBMK reactor according to the rules and standards accepted by lAEA and international nuclear society. Lithuanian regulatory body VATESI has issued operational licence for Ignalina NPP unit 2 on the basis of safety analysis report and independent review of it. (author)
