EFFECTIVENESS OF CESIUMBINDERS IN REDUCING CS-137 TRANSFER INTO BROILER TISSUES

For groups of male broiler (10 birds per group) were used in order to examine the effects of different Cs-binders in cases of alimentary con tamination with radiocesium-137. The first, control group received per os 3 ml CsCl solution per chick, total activity of 3120 Bq alone. The other three groups received the same level of contamination and diffe rent Cs-binders per os: second group-zeolite, third group - AFCF and f ourth group - Fe-ascorbate. Gammaspectrometric measurements of Cs-137 activity were performed on fresh homogenous samples of meat and edible organs taken 3 and 7 hours after contamination and protection. Zeolit e and AFCF showed significant protective effects. Reduction of radioce sium-137 accumulation in meat ranged between 60-70% and in edible orga ns it was greater than 50%, in comparison to the control group. Protec tion was shown by Fe-ascorbate, but the effectiveness was lower (20-40 %).
