Natural sepiolite efficiency ... activity concentration (Bq/kg fresh weight) was determined and reduction of 137 Cs deposition in the breast meat, liver and gizzard of broiler chicks was calculated in relation to the group 1 (control) expressed in percents (decreasing percentage relative to control). The experimental data were subjected to the analysis of variance using the STATISTICA for Windows Software (Stat Soft Inc. version 6). The significance of differences between means was tested using Tuckey´s Honestly Significant Test. Results and Discussion After oral contamination, radiocesium be deposited in soft tissues. The level of deposition in meat (breast and legs muscle), liver and gizzard of chickens, after 24 hours of contamination is shown in Table 1. Table 1. 137 Cs distribution and deposition into the meat, liver and gizzard of broiler chicken Tissue/ organs Meat Liver Gizzard 137 Cs activity (Bq/sample) Group 1 Group 2 ( 137 Cs) ( 137 Cs+sepiolite) 2090 ± 112 1660 ± 109 * 36 ± 6.1 32 ± 2.1 92 ± 8.7 81 ±7.7 Means ± Standard deviation; * Statistically significance of differences (p < 0.05) % of ingested 137 Cs activity Group 1 Group 2 ( 137 Cs) ( 137 Cs+sepiolite) 56.00 44.00 1.0 0.85 2.4 2.16 Obtained results showed that 56 % of introduced 137 Cs radioactivity was deposited in the muscle, 1 % in the liver and 2,4 % in the gizzard (group 1, only radiocesium ingested). In the case of oral simultaneous addition of sepiolite, 44 % of introduced 137 Cs activity was deposited in the muscle, 0,85 % in the liver and 2,16 % in the gizzard. The effects of the administration of sepiolite on the decreasing 137 Cs deposition in the meat, liver and gizzard of contaminated broiler chicks were presented in Table 2.

186 D. Vitorović et al. Broilers in group 2, which received sepiolite, showed significantly (p< 0,05) lower 137 Cs activity concentration in meat when compared to the broilers in control group (group 1), those who did not received sepiolite. Percentage reduction (decreasing percentage) of 137 Cs deposition in meat was 16 % compared to the control group. In cases of liver and gizzard there were no significant differences in 137 Cs activity concentration between group1 and group 2. Radiocesium decreasing percentage, relative to the control group, in liver was 5 % and in gizzard 12 %. Obtained results showed lower degree of broilers protection compared to those achieved with clinoptilolite Vitorović et. al. (2002), Poschl and Øezáè (2003), Vićentijević et al. (2006) and Mitrović et al. (2007). These aouthors stated that 137 Cs binding efficiency of natural and modified zeolite ranged from 50.0 % to 70.0 %. According to the researchers from Ukraine (Lonin, 2009) all substances with antiradiation properties can be separated into three categories by the protective action efficiency. The first category (insufficient protective action) consists of substances with protective efficiency of 0-30 %; the second category (efficient) consists of substances with protective efficiency of 30-60 % and the third category (high-efficient) consists a substances with protective efficiency of 60-100 %. On the basis of these divisions, natural sepiolite demonstrated insufficient protective action. Conclusion After 24 hours of contamination, 56 % of introduced 137 Cs radioactivity was deposited in the meat (breast and legs muscles), 1 % in the liver and 2,4 % in the gizzard of broiler chickens 42 days of age. Natural sepiolite demonstrated insufficient protective action. Compared to the control group, percentage reduction (decreasing percentage) of 137 Cs deposition in meat was 16 %, in liver 5 % and in gizzard 12 %.
