Abstract
In connection with the national nuclear power station programme a series of measurements was initiated to detect radionuclides in the River Danube. Examinations started in Spring 1978 at six sampling points along the Hungarian reach of the Danube. From among algae of various species of the Danube the localized and well-propagating filamentous green algae (Cladophora sp., Vaucheria sp.) were investigated. The activity concentration of gamma-radiating nuclides absorbed by algae was determined with a Canberra 8100 type Ga(Li)-spectrometer. This apparatus facilitated radioactivity measurements on wet samples or samples subjected to simple physical preparation.
The metabolic character and accumulative abilities of filamentous green algae showed them to be suitable indicators of radionuclide contamination of the water ecosystem. Results are131I nuclide at min. 72.5 mBq/g to max. 5440.0 mBq/g and other fission products from 55 mBq/g to 929 mBq/g.
