Comparative study of Cs-137 distribution in broilers and pheasants and possibilities for protection

Abstract

The aim of the present study was to investigate distribution of Cs-137 in leg and breast meat of broilers and pheasants following single alimentary contamination and administration of two protectors (AFCF and clinoptilolite). The birds were administered a single dose of (CsCl)-Cs-137, with an activity of 750 Bq. Protectors were given via gastric tube or mixed in the forage pellets. AFCF given via gastric tube decreased the Cs-137 concentration by a factor of 7.8 in broilers leg meat and 7.4 in broilers breast meat. When AFCF was mixed in pellets, the Cs-137 concentration was 19.5 times lower in broilers leg meat and 22.1 times lower in broilers breast meat, than in the control group. In pheasants, AFCF administered via gastric tube decreased the Cs-137 concentration by a factor of 12.4 in leg meat and by a factor of 13.7 in breast meat, respectively. In group 4, where pheasants were administered AFCF mixed in pellets, the Cs-137 concentration was 3.7 times lower in leg and breast meat, than in the control group. For comparison, clinoptilolite administered via gastric tube decreased the Cs-137 concentration 1.8 times in broilers leg meat and 2.0 times in breast meat, compared to the control group. In pheasants, Cs-137 concentration was 2.9 times lower in leg meat and 2.6 times lower in breast meat. Clinoptilolite mixed in the feed had relatively low efficiency of protection in broilers (Cs-137 concentration was 1.4 times lower in leg meat and 1.6 lower in breast meat). A similar trend was observed in pheasants (Cs-137 concentration was 1.6 lower in leg and breast meat).
