Calculating Ivalent Dose Rate Field Structure Applying the Method of Optimal Interpollation in the Baltic Sea Coast Optimalios interpoliacijos metodo taikymas lygiavert s doz s galios lauko struktūrai nustatyti Baltijos jūros priekrant je

Equivalent dose rate measurements were carried out in the Baltic Sea coast near Juodkrant . The measurements were performed at the ground level and 1 meter above it at 63 points within the territory of 2,0′0,2 km on 2 July 2008 and 10 July 2008 under conditions of northern and southern wind directions respectively. The extreme rates of the equivalent dose rate were 51 and 90 nSv/h respectively which means that the structure of the equivalent dose field was unhomogeneous. The method of optimal interpollation was used to calculate and evaluate the structure of the equivalent dose rate field. This method was used in 3 cases when 63, 33 and 18 numbers of measurement were carried out. The identical structures of the equivalent dose field were accepted. Using 18 measurement points, coincidence between the measured and calculated values of the equivalent dose rate was satisfactory. Difference between the measured and calculated values does not exceed 15% in 80% of the measurement points.

Matavimai atlikti 2008 m. liepos 2 ir 10 d. 63 ta kuose 2,0′0,2 km teritorijoje esant iaur s ir piet v jo kryptims. Vidutini dyd i ekstremalios reik m s buvo 51 nSv/h ir 90 nSv/h. Tai parodo, kad LDG lauk struktūra yra nehomogenin . LDG lauk struktūrai nustatyti ir vertinti buvo taikytas optimalios interpoliacijos metodas trims atvejams – kai tyrim teritorijoje atlikta 63, 33 ir 18 matavim . Gautos identi kos LDG lauk struktūros. Rasta, kad naudojant tik 18 matavimo rezultat modelyje gaunamas patenkinamas eksperimentini ir teorini rezultat sutapimas, t. y. j skirtumas nevir ija 15 % i 80 % duomen palyginimo.
