Background radiation on the territory of some military objects in Georgia has been investigated with the help of "DRPB-03" (dosimeter-radiometer) according to the specially created instruction. Background radiation of investigated objects varied from 0,09 to 0,28 mkZv/h; in average 0,18 mkZv/h. The maximal level was measured on the 8th object -0,28 mkZv/h, minimal on the 2nd object -0,09 mkZv/h, in average near the - 0,18 mkZv/h. The maximal level of the annual doze of radiation was measured on the 8th object -0,49 mZv/y; and minimal on the 2nd -0,15 mZv/y. The analysis of investigations showed, that the level of background radiation on the territory of the investigated military objects exceeds the level of European countries and South Caucasus (except Armenia). This could be explained by the peculiarities of our country: geomorphological structure and disposition of soil (altitude, latitude). These reasons could cause the high levels of natural background radiation. The level of background radiation is higher in Black Sea coast area, which may be the result of the Chernobyl Accident (contamination with artificial radionuclides). The comparatively high level of background radiation indicates that the personnel sustain relatively high radiation doses from natural radiation origins. |
