Sažetak
The study of transfer coefficients and concentration ratios of 40K and 137Cs was performed in order to investigate the bioavailability and potential analogy relationships of observed radionuclides in the chain of animal production of ruminants.
Sampling of material was performed at small individual farms situated inside the three regional livestock areas in Bosnia and Herzegovina.
Transfer coefficients and concentration ratios of 40K and 137Cs were calculated for beef and sheep meat. Obtained results were in accordance with literature data with average transfer coefficient values for 40K and 137Cs in beef of 0.017 and 0.058 d kg-1, respectively; whilst the same values for the sheep meat were higher (0.104 and 0.341). Average values for concentration ratios of 40K and 137Cs were equilibrated between the species (beef: 0.125 and 0.418; sheep meat: 0.136 and 0.443).
Obtained results indicated on the hidden analogy between observed radionuclides, covered by the homeostatic control of potassium in ruminants. The study confirmed the use of potasssium compounds for reduction of radiocesium contamination in ruminants.
