- Abstract
- The C-14 results from the study demonstrate that, although the liquid discharges from the Ringhals Nuclear Power Plant (NPP) are assumed to be small compared to the total operational C-14 releases, the resulting C-14 levels in marine biota can be substantially higher than in terrestrial biota. The fndings indicate that the chemical speciation of discharged C-14 plays a critical role in its transfer and uptake by marine organisms.
The highest concentrations of C-14 were observed near the cooling water outlet of the NPP. Organisms collected from a biofouling plate exhibited F14C1 values up to approximately 700% above the estimated marine background. Similarly, soft tissue from Symphodus melops (corkwing wrasse) showed up to ~400% excess,...
