Sažetak
Monitoring 14C activity in the atmospheric CO2 and in biological samples (fruits and vegetables) in the close vicinity of the NPPK was performed regularly since 2006 to estimate the possible influence of the plant on environmental 14C levels and the possible contribution to the effective dose of local population through food chain. Mean values of 14C activity in atmospheric CO2 in the years when the refuelling was not performed represent a barely visible increase in relation to the activities of 14C in the atmosphere at the control point. Immediately after refuelling the atmospheric 14C activity was increased for a short period of time. Spatial distributions of 14C activities in biological samples show the dependence on distance and orientation. In all campaigns the highest activities were obtained at the same locations in the SW-NE direction that coincided with the most pronounced wind directions. Estimated contribution of 14C released by NPPK to the natural dose is less than 1 μSv.
