Abstract: | Summary Technogenic and natural radionuclide content in red macroalgae (Ceramium rubrum, Corallina officinalisand Callithamnion corymbosum) from the Bulgarian Black Sea coast, collected in the period 1992-2003, was studied by low-level gamma-spectrometry. The
data show that the nuclide concentrations depend on macroalgae species and coast locations. The highest nuclide content was
measured in Ceramium rubrumspecies. The 137Cs mean value is 9.8 Bq/kg, 19.6 Bq/kg for 226Ra and 17 Bq/kg for 210Pb. The radionuclide pollution is considerably small due to the absence of nuclear facilities along the Bulgarian Black Sea
coast. |
