Sažetak
Measurements of 14^C activity of atmospheric CO_2, vegetables, and tree rings in the area of the 632 MWe power plant Krško in Slovenia, NW Yugoslavia, have been in progress since January, 1984. Sampling stations are located in the area ca 400km^2 and are distributed in the direction of the prevailing westerly winds. The closest sampling point is 1.5 km NE of the plant exhaust stack, the farthest sampling point is 30 km E of the plant. A sampling site at National Park Plitvice in central Croatia was chosen as the 14^C reference point not affected by the power plant. An average excess of 2.2% above the reference point activity during normal periods of reactor operation was observed 1.5 km from the plant smokestack. Calculations of the 14^C release from the power plant was estimated at 0.1 TBq/a. The tree ring activity near the plant followed the 14^C activity of the Northern Hemisphere in the past decade. No influence of the power plant release was observed on the tree ring activity.
